appears I get a "standard" error dialogue with the
following:

I managed to get to the call stack and eventually traced
this down
to a problem in _initterm() which is in crt0dat.c - MS
code that I have
NO IDEA as to what's going on in. As an aside, I've now
rebuilt this app
in release mode and the problem no longer exists, but I
still need it to
work in debug for obvious reasons. Does anyone have any
idea as to what's
going wrong here. I've stepped through the innards of
_initterm and it
appears to be doing a whole lot of initialisation - other
than that, I'm
stuffed as to whether I can work out what's going on - and
wrong.

If anyone has any thoughts on what's going wrong and
causing this
dialogue to pop up, it would be greatly appreciated if
they could share
the knowledge.

`_initterm' function calls constructors for all static
objects in a module. I opened "afxwin1.inl" on my machine
and it contains following ASSERT at line 24:

23 _AFXWIN_INLINE HINSTANCE AFXAPI AfxGetResourceHandle()
24 { ASSERT(afxCurrentResourceHandle != NULL); <--
Assert!
25 return afxCurrentResourceHandle; }

Obviously, it won't assert in release builds. You said that
you moved all strings to string tables. Can it be the case
that some global object tries to access resources from its
contructor before all necessary initializations are done?
