Thanks Zlatin, that fixed it! I had deleted all of the .fxps to no avail already. Why did checking the debug box fix it? Have I overlooked something basic? (I do that sometimes :0)

>>Hi all, I have been able until today to issue 'set step on' and step through my app in the debugger without any problems. Nothing has changed that I know of. The app's files are NOT in the same directory, but they are in the path. I have many sudirectories for my apps, but it was never a problem before. Any idea why all of a sudden I would get the 'source not available' error in the debugger when I wasn't before? I've verified the path. I've deleted and recreated the foxuser file as well as ensured that all temporary foxpro files were deleted too.
>>TIA,
>>Tracy
