Don't waste your time - AFAIK there's nothing you can do
to make MFC work reliably on threads not created via
AfxBeginThread. Get rid of it.

I have a free threaded ATL dll exposing one interface. I am using the
resources of a MFC dll for some very non-MFC things (no dialogs or
anything like that). When I am testing this application I am getting
crashes in the MFC dll during a DLL_THREAD_DETACH call right here in
dllmodul.cpp. I have looked around and I have seen several references
to "No MFC with MTA" so my knee jerk reaction is to re-write this dll
without MFC, but I don't want to waste time if it's something I can fix
easily.

Thanks,
Chris
