I am working on a Python 3.3 project that uses Tkinter as a Window manager. I have mouse scroll wheel events set up for a canvas. The scrolling works in Windows 7, 8, and Ub
This looks like the problem described here. If you are using the python.org 64-bit/32-bit installer for 3.3 (currently 3.3.2), make sure you've also installed the latest ActiveTcl release, currently 8.5.13, as noted here.
