Ah, thanks for the info.  When I searched for how most window  
developers handle having only one instance mutex objects seemed to be  
the most popular.  I guess this makes sense seeing that mutex applies  
to apps and critical sections to a single process.  In any case, it  
was much easier to implement then I thought it would be.
