I've got an vfp5 app which runs fine on all windows systems except for some XP. The main symptom is that on start up users get I/O error 23 or similar. We ship vfp5enu.dll, vfp500.dll & comctl32.ocx. Should we also be shipping vfpole50.dll?

we put them all into the system32 folder.

I've also heard:
"By the way, if any modules depend on Visual Basic runtimes, there are some issues with differences between the XP versions and previous ones. You can correct many of those problems by running an application in "Application
Compatibility Mode"

Does VFP have any similar issues?
