Fixing Leo and Idle OS shutdown bug?

I'm having no trouble using the described api to intercept WM_DELETE_WINDOW
events with Leo. I confirmed this by opening a tkMessageBox in the callback
routine. Worked each and every time on a variety of "new" and "open"ed
windows (i.e: file menu invoked windows), as well as the main startup
window.

This is on windows 2000 with python 2.2.1 and leo 3.4 beta 3 (or 4?)

Sometimes the wingnut between the keyboard and the chair gets loose - have
you checked for that? ;-)
