I have crash dump files generated by DebugDiag where the STATUS_FATAL_USER_CALLBACK_EXCEPTION is occurring. This one occurs during shutdown of our app and happens if the .NET runtime is shutting down.

Crash is in CXTPSingletonPoniter::GetInstance where CJ specifically throws a memory exception.

Has anyone seen this? Is CJ leaving a windows hook hooked up too long?
