Application not front-most anymore

[depstein at att.net]

I think you want "suspend" and "resume" (not "suspendStack" 
and "resumeStack").  MC 2.5's help stack treats each of these pairs as 
synonyms, but this looks like an error.  My experience is that "suspendStack" 
is sent whenever you leave a stack (to go to another stack, or to another 
application); and that "suspend" is sent only when you go to another 
application.  And that the same distinction applies to "resumeStack" 
and "resume."  If you don't want to catch the stack-switching within MC or 
your application, use "suspend" and "resume."
