Ok thanx. I didn't think about that. The only thing that puzzles me is 
why the vmt's will be different? If you allways use the creator routine 
(which is exported by the library) aren't all classes created in the 
same memory space etc?  Shouldn't that also mean that the VMTs are the 
same? Or am I missing the crucial point here?

Thanx
