[issue834351] Mouse wheel crashes program

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

3.0.1, WinXP, with two 3.0 revisions:

from tkinter import *
def _onMouseWheel(event):
    print(event)

root = Tk()
root.bind('<MouseWheel>',_onMouseWheel)

In IDLE shell, nothing changes, wheel works normally.

In interpreter window, wheel continues to work normally.
After click on tk window, wheel generates
<tkinter.Event object at 0x00ACE970>
messages in interpreter window.

Unless someone can verify that there is a problem in 2.6.1, or in 3.0.1
on other hardware, we should close this.
