When we use the fast user switching (WinKey + L, then log back in as same user) in our application we get a crash with the call stack

Is is very possible that this is a problem in our application, but if you also do a fast user switch with the GUI visual studio 7 example program the output window is not redrawn in the correct font, so there may be something wrong with the toolkit.

This problem has been corrected with the upcoming release

You can fix it in your source code to remove unnecessary VERIFY macros in
