My project consists of a standard .EXE,  ActiveX .DLL, Standard .DLL
(written in C) and a couple of home grown .OCX's.  All of these are in
separate .VBP projects (except the standard .DLL obviously because it
is in C).  The objects that reside in the ActiveX DLL are instantiated
in code in the standard .EXE.  The ActiveX DLL makes calls to the
standard .DLL and return data.  

In the IDE, when running the standard .EXE, everything runs fine.  The
objects are instantiated correctly, the calls to the standard .DLL
work fine, etc...  However, when I put the standard .EXE and ActiveX
DLL into a project group (.VBG) so I can do some performance tuning on
the .DLL,  VB crashes on returning from the call to the standard .DLL.
I get a GPF from VB, not my application.

The projects are controlled by sourcesafe, therefore they are in
separate directories.

Any ideas on this problem ?
