This title is follow-up of "AppVerifier and WinDbg with VB6 are killing me" http://msdn.microsoft.com/newsgroups/managed/default.aspx?&guid=&sloc=en-us&dg=microsoft.public.win32.programmer.tools&p=1&tid=d5437651-e83d-460c-9316-1bf55e933ecd Thanks to Prasad, I learned that error was caused by the bug in MFC. I reported this to the gentleman in VeriTest. But he replied, "Considering the sheer number of tests that we conduct on XP, I cant imagine that we would have a critical error caused by a bug on that platform." Has anybody seen this kind of MFC bug before? Is this bug catchable by VB6? I really cannot figure out how to catch this error. Anybody can help? Thanks for your help. Jianke
