I haven't seen anyone respond to this yet, so I'll give what little information
I have. I hadn't responded earlier, as I don't know the full details of the
problem, and hate to speak knowledgably on things I don't know about.

I think that this whole thing was an attempt to fix a bug in the dialog 
manager. It was leaving 'dctb' resources in memory after the dialog was
disposed of. Apparently, the fix involved a patch to GetResource that would
detach the 'dctb'. This is what leads us to the current problem.

Needless to say, we in DTS were upset about this when we found out. There were
many developers that were messed up by this patch. I think that some guys here
are working on another fix that should fix the fix.
