Problems Opening Data
Data must be stored in a sub-directory, not in a root directory. So, for example, you cannot open data stored directly in the root directory of a floppy disk. If backing up to floppy disks or Zip drives then always store data in a subdirectory - you could use the name of the site as the directory name.
Geoplot 3.0 supports parallel and USB printers. However, if you connect a parallel port printer to a USB port via a USB/Parallel port interface you will in general need to change the Details entry on the Properties form of the printer to redirect printing from the parallel port to the USB/Parallel port interface adapter.
If you are attempting to print to a network from a Windows 2000 terminal you may only be able to print once before getting a printer error message. To work around this, set the default printer to a local printer and then use the Net Use command to redirect printing from LPT1 to the network printer. An example command line is: "net use lpt1 \\geoscan1\epson_q". Create this in Notepad, save as a batch file, eg redirect.bat and create a desktop shortcut to it. To cancel this command create another batch file: "net use lpt1 /delete".
If you change printer settings, eg paper size, sometimes this change will not come into effect immediately but will only come into effect on the second time of submitting a print job.
In general, single users with a dongle protected Geoplot cannot print directly to a network printer since the dongle will only work correctly when the parallel port system is disconnected from the network. Instead you must either use a local printer attached to the parallel port and dongle or enquire about network versions of Geoplot which are protected with a software lock.
If you are unable to access the printer when using a hardware lock and conventional parallel port, even though Geoplot runs correctly apart from this, then it is likely that the printer driver is the cause of the problem. Some printer drivers, especially those supplied with Hewlett-Packard printers, are set up for bidiectional use, with the printer trying to send and receive information on most of the parallel port lines all of the time. If the dongle and printer try to access the same line then problems can arise. The solution is to disable this bi-directional mode of operation using configuration settings in the printer driver - please consult your printer driver technical guide for details on how to do this. You will probably need to reboot the PC for any changes in printer driver settings to take place. By changing the bidirectional settings you are unlikely to loose any major functionality - for example you may simply no longer get a report of the amount of ink left in the printer cartridges. If you cannot resolve the problem by making such changes and have a dongle with a number earlier than 98167 then we may issue you with a new dongle and disks. Note however that a new dongle will not necessarily cure any dongle and printer driver conflicts. It may be necessary to issue you with a software lock instead to overcome such problems.
If you experience general printer problems even with a software authorisation then try installing a generic printer driver for your printer, eg Epson Esc 2 for many Epson printers and set this as the default. If this solves the problem then you should try and obtain an updated driver for your printer.
Problems with Graphics
If you get a specific error message concerning graphics, for example advising that the plotting parameters should be changed, but doing so does not improve matters, then try Clipping the data beforehand.
Less specific graphics problems are generally caused by the driver for the graphics card so make sure you have the latest driver installed. For example you may have a problem using Save Graphic Plot - other programs are unable to read the resulting file - or the graphics image is "dithered", even at 256 colours. If you are unable to change the graphics driver it is possible to allow other programs to read the file by first importing it into Windows Paint and saving it in Paint.
If the saved bitmap image is distorted (graphics image in the wrong place or segments swopped) when running in 24 or 32 bit mode, changing your display setting down to 256 colours will remove the problem.
When saving Trace plots for export or use in Publish, use Resolution = Absolute for consistent plots.
Problems creating Composites from Master Grids
If you experience problems creating composites from Master Grids it is very likely that you have stored the master grid in a sub-directory with a name that does not match the grid directory - see "Creating a Master Grid" in the Tutorial section for further details and an example. Note that all grids referenced in a master grid must be located in one directory only. If you wish to combine grids located in different directories you must first move them all into one common directory, renaming some if there are duplicate names.
Problems with Publish
If you import a dot-density plot followed by a shade plot then a printed dot-density scale will be empty. To work around the problem reverse the order of import ie import shade plots first, then dot-density plots.
Text in Publish must consist of more than one character otherwise it may not be printed. If you wish to use just one character then, as a work around, add a decimal point after it to make it printable.
Although a published document appears to be complete on screen, it is actually stored as a text file that defines the relative positions of all the objects that you see on screen (and on paper). The text file refers to graphics plots, bitmaps and metafiles by their path names - it does not actually embed graphic images in the document file. It is therefore vitally important that the original file can be located whenever you open up a published document. Bear this in mind when backing up data, restoring data or relocating data. If the file is no longer at its original location the published document will not open properly. In this case use use Notepad to open up the .pdo file and check the paths of the graphics files referenced. If printed publish documents have a white or grey rectangle where you would normally expect a graphics to be then check the file paths as just described.
If any publish objects appear to be corrupted, for example a scale bar appears to be just an empty rectangle, then save your published document, restart Geoplot and reload the document to clear the error.
The aspect ratio of imported metafiles may be incorrectly set as square. Right-click on the object to show its properties and resize to the correct aspect ratio.
Problems with Process
It is sometimes possible when you are using Periodic Defect Filter to get an "incorrect frequency index" message even when you are using a valid frequency index. This arises only when certain graphics magnifications are being used. Should you get such a message you should reload the original data set since the data in memory may well be corrupted if you see such a message. Change magnification before trying to use Periodic Defect again.
Problems with Import
If you keep getting the message that the import parameters do not match the file size then check the import file using a text editor such as Notepad to ensure that there are no extra characters or lines at the end of the file.
Loss of Floating History or Statistics Forms
If you reduce screen resolution and previously had the floating History or Statistics forms near the bottom of the screen they may no longer be visible. To restore them either (a) increase resolution again and move them higher upt the screen before reducing resolution or (b) replace the hist.ini and stat.ini files with the default files provided in RestoreFiles on the Geoplot CD or (c) open up hist.ini and stat.ini in Notepad and edit these files so that they show "1000 1000", ie new X,Y coordinates that should place them back in the visible area.
Problems running under Windows 98 and later
The palette list on shade plotting parameters and options forms may take a long time to settle. If so, then turn the Animation effect off to greatly speed up the response time.
Problems running under Windows 2000 and XP
Geoplot functions correctly in Windows 2000 and XP when using a software lock though some form labels may appear to be of a slightly different shade of grey. The Process and Drawing toolbars may not align properly with the top toolbar in 2000 and XP. If that is the case choosing to run Windows in "Classic Mode" will restore proper alignment.
Under some circumstances the defragmentation utilities supplied with Windows 2000 and XP can corrupt the Geoplot software lock authorisation - however this is not a problem on all systems. To be safe, and where possible, you should not attempt to defragment in 2000 and XP. This problem is currently being investigated by the suppliers of the software protection scheme we use and we hope to have a fix available shortly that will allow defragmentation on 2000 and XP at all times.
Problems with Networks
If you are prevented from logging on as a specific user number, because Geoplot reports it is already in use, yet you know that it is not in fact in use, then a file called loggedon.ini may be present in the options directory for that specific user - see Appendix B, Installation Files for a description of the location where this file will be found. The file loggedon.ini should normally be erased whenever a user logs off, but if the program crashes, the process that erases that file will not take place. Removing the file manually should cure the problem.
If Geoplot reports missing files then you will need to copy / move / remap (depending on what your network system allows) the files listed in Appendix B, especially the Options files in which individual user preferences are stored and their log-on file is stored. Individual users need to access the contents of the following directories (shown with a default C drive) as listed in Appendix B of the Geoplot manual :
Optionally, but strongly recommended, users should also have access to the contents of the following directories to enable them to follow the tutorial and examples :
Once copied, moved or remapped ensure that the Default File Paths specified in the Options menu match the location where the above files are stored.
