Has anyone out there been successful in using the Implements command in VB 6.0?

We are attempting to use it and whenever we change a method's signature or add/remove new methods, recompile our DLL, and attempt to run we end up gettinga GPF that brings down the application - and VB if it is running.

We can successfully run our source code in VB 5.0 but not VB 6.0.

Has anyone else had any experience with this problem?

-- Thanks in advance,
Jeff
