Kenneth,
The Dr. Watson error message means nothing to me too.
Sometimes, if a Paradox Form or Library was compiled and saved with the
"Compiler Warnings" and/or "Compile with Debug" options checked... you can
experience erratic errors or GPF errors. Try opening the Form and or
Libraries it calls in Design Mode and check if these options are checked.
If they are checked then uncheck them then compile the file again and save
it. Do this for the Form and any Libraries that it might open.
If that doesn't solve the problem and no one else jumps in with another
idea... then I would consider the idea that possibly there is a corrupt
file(s) within either the Paradox installation or the Windows OS
installation.... or you are experiencing an intermittent hardware failure.
I would first consider the easiest approach by removing Paradox 100% from
the PC then re-installing it from scratch. Make sure to add any updated
Service Packs to Paradox after re-installing it and reconfigure the BDE so
it's identical to other PC's (of the same OS) that are known to work. Make
sure that access rights are set high enough for the required Paradox
directories.
If that doesn't fix it, I'd then consider the idea that the Windows OS might
have corrupt files and possibly re-install it... The best results is to
reformat the drive and install Windows from scratch... This is a "Drastic
Action" and may require considerable time and pose the possible loss of
critical programs and data. You will need to get ALL the service updates
for Windows from MS, etc. etc...

(
Before you do any of these things... hopefully someone else here will jump
in with a less aggressive solution and save you the headaches involved with
my suggestions.
My reasoning is this... if all things are equal (the PC's settings are
identical to working PC's with the same OS) and you are still getting GPF
errors on the one PC... then the problem is either corrupted files or
failing Hardware.
An example of failing hardware.... I've seen problems like this because of
a failing CPU fan... The fan was still spinning, but not fast enough to
keep the temperature of the CPU cool enough... The over heated CPU caused
error messages and corrupted file writes to the HD. After replacing the
fan, the errors went away.... but the OS files by that time were minced
meat... I had to re-install the OS. My suspicions were directed towards
the CPU fan after I noticed the audible sound of its failing bearings.
For your sake... hopefully someone else here has a better idea and you will
not be faced with re-installing Windows.
