>One last comment before I do this (or what Jeff suggested) ... I still think there's corruption of the .SCX somehow. I don't think I mentioned this yet, but clicking on the form the first time from the project, brings it up ok. Then close it (no save prompt anymore .... thanks for that suggestion, Bruce), then click on it again in the project .... BOOM!! Immediate C5!

Try this, to see the effect:

Create a new project. Add only the bad form to it, and test the problem, just to be sure it's the scx that's rotten and not the project...
