it's a problem with older versions of Tkinter (2.2.2 and older) with
newer versions of Tk (8.4.2 or later).

I think this is fixed in 2.3b1; if you cannot upgrade Python, you might
have to downgrade Tcl/Tk (8.4.1 or earlier should work just fine).

(for some strange reason, the Tcl/Tk folks don't care much about
compatibility; they're even changing C function signatures from one
release to another...  too many amateurs involved, obviously)
