When opening a program, VFP doesn't release the handle on the file even after the program is closed.

Ex.:
- MODIFY COMMAND MyFile
- Close MyFile
- Try to delete MyFile.PRG from Windows Explorer, you get a "File is in use" error

What command, other than QUIT, will force VFP to release the file handle? I tried CLOSE ALL, CLOSE PROGRAM, CLEAR ALL, RELEASE ALL, RELEASE ALL EXTENDED and FLUSH without success.

TIA
