Fatal Exception on a machine with Win98 version 2

[MikeDav]

Can anybody help???

On a distributed VFP 6.0 application we are getting this error:

Fatal exception 03 has occurred at 0028:C0059820 in VXDVMCPD (01) + 00000360

The machine in question is running Win98, version 2 and has 64 meg RAM. The users are running Outlook 2000; might there be a conflict of some sort?

We tested out our application on Win98 prior to release and all was OK on our Compaq Deskpro. It also runs just fine on NT, 95, and it was tested successfully on 2000. We have nearly 400 users in the field running on just about every type of PC possible and this error has just popped up.

At a convention last week, the same thing happened to me on a 98 macine, so we swapped out the PC for one running NT with no further problems.

Any clues?

Mike,

- What Are Fatal Exception Errors. Interestingly they don't list "03", but I've occasionally seen it in relation to video problems. Check the suspect systems for out of date video drivers or non-standard video chip sets or boards. Also many drivers are only "tested" for specific (read limited) video resolutions and/or color depths - try the application at 640x480 and only 256 colors (or what ever the lowest values allowed are) and see if the problem goes away.

Note: VXD's are virtual device drivers and NT/2000 don't use them.

Also, I've found that unless the VFP application is very small, you either need to run it all by itself, or upgrade to more than 64MB (especially on "cheaper" machines that sometimes use system memory for video memory).
