Hiya,
I have a problem with my application.  It hangs around in memory after
exiting (and the debugger thinks its still running; I am unable to "break"
or "stop" execution).  The main loop below shows my "main" function.  When

Accepting the fact that .NET 1.x is lacking support for named events, and windows security manipulation, we end up using interop and the platform SDK, and functions like CreateMutex and OpenMutex. And it's with OpenMutex that I'm having a problem.
In summary: I'm creating a mutex ...
