Unless I misunderstand what you've done, you're processing any and all
messages here.

What this implies is that you've got this loop that runs, effectively, as
a background process WHILE ALL FUNCTIONS OF YOUR PROGRAM ARE OPERATIONAL
AND ACCESSIBLE TO USERS -- i.e., you can (recursively) call any function
within your software.

Did you really intend that?  What you desribed led me to believe that
you just wanted to let other Windows programs (not yours) run while
you finished this loop.  I concluded that your program itself was "busy"
during that time.  If that's really what you wanted, then you'd best not
allow any message at all, just the ones related to focus.
