v5.8.8 on Debian works exactly as I would expect. 5.6.1 on windows gives
me grief. Looks like it's time for an upgrade.

Yes, looks that way. I'll be looking at onDestroy() as well.
Thanks to all who chimed in.

I have tried your example on both OSX and Windows and it is giving me
the required behaviour. When I click the Exit button on the child
windows I get a message on the console saying 'fred is being destroyed'.
The message isn't always immediate but it does appear as a result of
clicking the Exit button on the $tl windows.
I was using perl 5.8.8 and Tk 804.028 on the Mac and perl 5.10.0 and Tk
804.028 on Windows.
HTH,
Matt
