Jason,
Ok, I will test with a recompile with Run-Time but I don't undestand what
you mean by a "difference base of code".

Perhaps you have a difference base of code between the running app and the
one you are plugging in with. Run-time packages ensures that you are using
consistent code between the modules compiled separately.
