Q.  AfxGetMainWnd() is returning NULL.  What can I do about this?

A.  Apparently it returns NULL when called from a thread other than the main one.
Which means its not very useful.  Before Visual Studio 2005 it worked fine.
Use this function instead:

inline CWnd *MyGetMainWnd() { CWinApp *app; if ((app = AfxGetApp()) == NULL) return NULL; return app->m_pMainWnd; }
