Hi guys.

I was hoping to use the cscroll.tcl demo to sort out why the scrollframe by Ulis at http://wiki.tcl.tk/9223 (a similar canvas implimentation) wasn't accepting and acting on MouseWheel events.

However, on testing with both X11 and Windows, the Tk demo cscroll.tcl's MouseWheel events are only acted on if the platform is Mac (Aqua). Elsewhere, MouseWheel events are ignored.

    This is because you require focus on the widget for the mousewheel event to be caught. I had hoped to correct that with better global mousewheel behavior in tip 171, but that didn't make 8.5.
