graphics getting stuck?

[ajo]

Since I have had my iMac, now and again, it happens most with iTunes, if I go to a different space or switch users etc, when I come back if iTunes is open, instead of seeing coverflow half the window is just the normal list. This is, until I click on the bit that is just the list and it goes back to coverflow.

Am I the only one with this problem?

Thanks
