iTunes display freezes when minimized

Update...

I was rushed when I last posted, so I wanted to add a few more details (and a better picture). When I first installed iTunes on my new Vista laptop in August 2008, I had no problem with the screen freezing up. It wasn't until the first iTunes upgrade that included "genius" that I began having this screen freeze problem (this is why I've included my post in the upgrade section).

I've uploaded a new picture.

In the picture, the song information at the top of the iTunes screen is correct, but the "now playing" image is not. This generally happens when I open another window/screen on top of iTunes, work on the new screen for several minutes, and then close the new screen. The iTunes screen is almost always "frozen" at this point. To unfreeze the screen I just have to click anywhere in the iTunes window, but it is a major annoyance, especially on a new laptop; I've upgraded since then, and all new versions of iTunes have the same problem on my computer. No other program does this.
