Michel,
I seem to remember something similar to this and I think the work-around I found was to add several new lines in my code (empty lines empty space) and then build. I know it sounds crazy but I swear it solved my problem at the time. If I recall correctly it happend while I was building the MTDLL I used for an ActiveVFP web application (www.TaskASAP.com). I also think it was someone here on UT who gave me the suggestion to try adding empty lines.
Hope it helps.

>I had this situation after a while with VFP 8 and now still have it with VFP 9. Basically, I have an application that works fine. I can start VFP, modify my project, build it and run it. It finishes ok. Now, I am back into the modify project and try to build it a second time. VFP will simply freeze. I think this is also related to the same problem that my application, when being run from the desktop, from Main.EXE, will not terminate once I finish. The application will remain in the task bar for about two minutes until it goes away by itself. I only have this since I have upgraded to XP. I never found the problem. However, now I have this VFP project that I need to work on and just can't afford to close VFP everytime I run the app before building it again. We talked about that a few months ago. I never found the problem but now I need to resolve that issue once and for all.
