I think this is a minor bug, but it can be pretty annoying. I normally keep iTunes open on my second monitor so I can have easy access to it. Up until the 7.x series of iTunes, I was always able to use the scrollwheel on my mouse. Now it will only work if iTunes is on the primary monitor.
Has anyone else run into this? I searched through the forums and couldn't find anything, sorry if this is a repost. Btw, I'm on an XP machine, I haven't been able to test it on a Mac.
Like I said, its a pretty minor issue, but it would be nice if someone had a workaround/fix for it. Thanks!
