I adapted your suggestion slightly, and my final event loop looks like this:

while not mainwin.hasQuit:
    try:
        gameLoop()
    except pygame.error:
        if not mainwin.hasQuit:
            raise
    pygame.time.wait(10)
    try:
        mainwin.update()
    except Tkinter.TclError:
        if not mainwin.hasQuit:
            raise

That seems to work perfectly. Thanks, Eric!

Ah, yes, I had managed to find the pythonware.com pages in my travels, 
and they proved quite helpful. Good to know about the man pages, too. 
(When I'm starting on a language feature, though, I usually find I learn 
a lot more from worked examples than from straight command information. 
I have friends who are just the opposite, so I suppose it's just a 
learning styles thing.)

wxPython seems to be highly regarded. I might experiment with that for 
my next project, and see which framework I like the best. Thanks again.
