Didn't do it all of the time, just often enough to be an annoyance. The only way to resolve it was to Build the App with Recompile all files checked. That always ran successfully. Then I would able to compile the exe. Since the work-around was pretty painless, never did resolve what the issue really was.

That was the weird thing. We compiled the exe with Recompile All checked too. Never had a problem building App, only occasionally the exe and never after a build of the App.
