If that helps: This is what Python 2.3 will do on Windows: ship with
Tcl 8.4.

Unfortunately, it is not. Tk decided to set some "indeterminate"
fields in event structures to '??', whereas earlier they have been
numbers. This has caused an incompatibility in Tkinter of Python 2.2.2
and earlier, which now crashes when trying to convert these to
integers. This has been fixed in Python 2.2.3 and 2.3, by not trying
to convert these fields, so that now Pmw crashes when interpreting
these fields as integers (where "crashes" means "raising Python
exceptions").

Regards,
Martin
