I've found that the generation of the <Configure> can also change from OS to OS, and from system to system with the same OS. Tkinter on Windows seems to only generate the <Configure> when you are finished resizing (which may or may not be what you want), and some Linux/Solaris/OSX systems generate it (a lot) while you are moving the mouse (which may or may not be what you want). I don't know how to change it, but I think generating the <Configure> while the mouse is moving may be a configuration option of X11, so you may have to allow for either case.

I tried overriding config (configure), but it is not called during resizing. . . . Is <URL: http://mail.python.org/pipermail/python-list/2007-January/ 424098.html >
