I know i am coming late to this party but I just downloaded the compiler this morning, got the QMBCform error and followed this thread. I wanted to add my results in case you were still interested.
I have XP Home Ed. w/SP3, and Office 2000 no SP's
Both of the test versions you linked above worked so far, at least they opened the form with no error message.
Thanks for all your fine work. As a newer fish in this big old pond I think it is wonderful how much creativity and assistance is out here.
