Thanks for the reply! I've had the problem you've described before too, so that was one of the first things I checked. I'm beginning to think it's poltergiests or something! =)

Thanks for your help!

>This is probably too obvious, but it's gotten me. :) I modify code in one copy of VFP and run SBT in another. If I forget to close the code in the modify copy, I get that error when I try to debug in SBT.

>>VFP is not allowing me to debug my apps. If I put a set step on, or a breakpoint in a program, it opens up the debug window (like it's supposed to). But all I get is "Source not available". I deleted the .FXP's just in case and tried it again. Same thing. I re-installed VFP. Same thing. Then I just created a new program and copied the old program's contents over and ran it that way. It worked! Once. Then I get the above error again.
