not half as much as I hate to hear it! :-(

I have already tried variations on this theme. Not least of which was putting the real library into a safe place and copying in a virgin copy of the FFC "_base.vcx" library and recompiling the app with that one instead of my library. It STILL protested that the library was corrupt - which is why I don't believe it. I suspect something along the lines of a screwed up reference somewhere in the app to something which it thinks ought to be in the class library but isn't. Is this possible? (in other words would it produce the same error?) or am I barking up a completely wrong tree?
