It looks like the problem is losing focus as mentioned by Peter Fales. I can
set a breakpoint in NtCreateFile, NtReadFile, and everything is fine up to
there. Once I exit NtReadFile though, the TroopMaster loses focus and doesn't
respond to keystrokes or the mouse. The window does refresh, but that's about
it.

Another case where TM gets hung is if you try and look at the DotNet log 
(File->TroopMaster DotNet...->View Log File) This is basically the same
situation where the program is downloading data from the server and loses focus
after it's done.

Still haven't figured out how to fix it though :-(
