[vtkusers] Mouse wheel events not working under Win32?

[Mathieu Malaterre]

Charles,

	On Win32, I used to play with wxWindow/wxWidgets, so I don't know about 
MFC. Did you try a google search, I found:

http://awc.al-williams.com/tips/tip26.htm

	I bet this is something really simple to be done in the example for the 
event to get passed.

I'll look into it tonite,
Mathieu
