Sorry for interrupting but i might be able to help. I have a main program
that runs forms from Packages and i use BC++5 Pro, during development and
Testing of the main program i got several unexplainable Access Violation
and Read of Address FFFFFFFF.

I traced the errors to the following:

1. Make sure that the IBO packages are compiled for RELEASE and NOT DEBUG
(Not Necessary but it helps).

2. Make sure that under Project->Options->Advanced Compiler, The
Instruction Set is 80386 for the IBO Packages (Necessary).

3. Avoid using "__stdcall" for functions that are exported (Can cause
problems if using LoadPackage() call).

4. Make sure that under Project->Options->Advanced Compiler, The
Instruction Set is 80386 for all the Packages and the Main Program (Necessary).

Hope the above helps.
