You can copy and paste the content of the debug output window... but then if it builds fine with it open, it would probably show everything OK.

Few things to look for: check the Show Errors checkbox when building, and Recompile would also be a good idea. Also, packing the project (Clean up project, as it's called in the menu) might help. Try to remove any project hooks - though it's a shot in the dark, don't see how they may benefit from debugger.

Worst case, build a new project from qms.prg and up.
