[Pythoncard-users] Added MDI support to Pythoncard (was MDI - childwindows within a window)

Hi John.
Awesome! Good to know someone is still developing PythonCard! PythonCard
is really a super project, for infrequent programmers like myself looking
for a Visual Basic-like development experience on Python, PythonCard does
the job.
I don't suppose you could shepherd through a new release? The current
release is several years old IIRC, and the installer has issues (either with
Vista and/or latest Python, can't recall). Most people who research
PythonCard these days just assume it's a dead project.
