>What should I be looking for with the temp files? How does it differ from VFP 6? I didn't have to do anything special with my VFP6 .EXE's other than install the VFP6 run-time. I have installed the VFP7 run-time but that doesn't correct the problem.

Check if temp directory has System or Hidden attributes. It's known to cause problem in VFP7.
