I hate when that happens.

VCX's can't be called like that (as you've found out). Forms are also an issue. Functions seem to work fine. I don't think I've tried replacing an entire VCX but I tend to embed a DoForm() function in which can call a form (and have it still be able to see the other libraries). I also tend to embed a CreateFactory() method which creates an instance of a class for me (and gives a central place to set various properties). Both could be used to call out to an external PRG/Class/Form.

If you have a hook point, you could try attaching a simple object to the _screen object that has the new code for the method you want to override. Then, use BINDEVENT to capture the method that has the bug in it and redirect it to your _screen object. You can get a form reference via AEVENTS, if necessary.
