The problem is definitely because it is an olecontrol. If I add a new class "foo" based on, say, a button, then "ADD CLASS foo OF lib1 TO lib2" works. If I create a new class "fee" based on, say, MS ListView6, then "ADD CLASS fee OF lib1 TO lib2" will fail with the message "Object class is invalid for this container".

Any help would be greatly appreciated. I can cut and paste everything in, but what a pain!
