When you get "booted out", is there any sort of error message? For example, if it's a C5 error, Windows will forcibly close it and give you an error dialog with some further information.

Some other things to try:

- If you run ?SET( "RESOURCE", 1 ) in the command window do you get the result you expect?
- Simplification: Do you use any add-ins in VFP such as Thor, or a framework IDE enhancement? If so, can you disable to test?
- Try temporarily disabling real-time antivirus scanning. Also, are there any other apps or services running on your system which might interact with the file system or running applications (such as "real time" or "continuous" backups, Windows File History etc.)?
- From an elevated command prompt, run CHKDSK to make sure your computer's file system is healthy. If it's OK you should get a message something like "Windows has scanned the file system and found no problems. No further action is required."
- If you haven't cleaned them up for a long time, your computer may have accumulated a lot of temporary files. You can manually delete ones you no longer need by RUNning (WindowsLogoKey + R), %temp%. This will open File Explorer in your Windows temp files folder. Having a ton of temp files can hurt performance
- You can run the Windows System File Checker (sfc). From an elevated command prompt, run "sfc /scannow" (without the quotes). This takes a while, even on a fast computer

I'm somewhat reluctant to suggest re-installing VFP, because that will probably undo any customizations you've done such as installing service packs. But if all else fails and you have a clear path to get back to where you were, it could be an option.
