Mouse Scroll Wheel not working when iTunes is on secondary monitor

Hi,
This is a pretty convoluted problem, but I run two monitors (from the one RADEON videocard) and it seems that the iTunes7 window won't recognize input from my mouse's scroll wheel when the window is positioned on my "secondary" monitor.

I know, it's weird, but it's the case.

I guess this counts more as a bug report than anything else, but I'm hoping something can be done about this soon!

I think it has something to do with the fact that any window to the left of the primary monitor uses negative coordinates to map its relative position on the screen. The scroll wheel functionality may be expecting positive positional coordinates in order to function properly.

At least, that's only a theory based upon my knowledge of Windows machines. Has anyone had this problem on a Mac?

Good call. I can confirm that the scroll wheel works any time that your mouse is in a positive coordinate location, does not work in a negative coordinate location. It doesn't matter whether the window straddles the two monitors - only what the mouse coordinate is. This applies for left monitors and (not nearly as common) monitors on top.

This goes to show that it's generally a bad idea to rewrite your own scrolling windows - you're bound to introduce bugs for some combination of input/output devices.
