The problem is generally that some _other_ application is running on
your machine that is not processing messages. This is a common problem
with DDE applications.
One good example is MSVC. If you are using MSVC and at a breakpoint,
Pythonwin will not start. When you stop the debug session, Pythonwin
then pops up.
You can avoid this by running "pythonwin.exe /nodde". However, this
will *always* start a new instance of Pythonwin.
