Hi david,

Please have a look at the callstack . Hope this would help you in
finding the solution.

It would help to see the source code at each of these lines. Starting
towards the top, why is CDocument::AssertValid() calling
CDocument::GetNextView()? Does the document really contain non-views
(otherwise why is IsKindOf() failing)? Very bizarre. At any rate, since
this also occurs other than when you receive a posted message, it does seem
some of your threads are leaving the state of your CView's a mess.

Sorry I can't be more help.
