iTunes (or something) freezing my imac!? what should i do?

[imac123]

Was working on my imac (3 week old 24" alu refresh), everything going great, I bring up tunes and put it in the mode where you can see album artwork. Then I click "get album artwork" for a couple of albums, no problem, a couple of seconds later... FREEZE

I can move my mouse around the screen, but everything is frozen and non responsive. I waited about 3 mins then just restarted. Open up iTunes, and do a similar thing, and FREEZE again the same thing (just a couple of minutes after restarting).

My current temps are;
CPU 44 deg C
Hard drive 50 deg C
GPU diode 57 deg C
GPU heatsink 49 deg C
PS 73 deg C

I have smcfancontrol at 1300/2500/850 for CPU/HD/Optical

Has anyone else had a problem like this w/ iTunes??? I don't know if it's iTunes for sure... could have just been a coincidence that I was doing similar things each time it froze.

What should I do in that situation?? Is there a mac equivalent of CTRL-ALT-DEL ?? I know there is a force quit option but in order to do that you need to click the apple logo first, and I couldn't even do that in this case.

Should I be worried that there's something more serious wrong w/ my computer?? Is there a way I can try "repairing" iTunes w/o deleting all my files?

Force quit short cut is cmd+option+esc

And mine also does that but its a MBP and not necesarely on full screen coverflow. The screen freezes if I'm playing audio it keeps playing, the cursor moves but everything else not. And I cannot force quit anything. I have to power it off. Very annoying. Took it to the genius bar and they told me that it is my third-party ram is not full compatible I havent tried testing it with the original one tough.

i see...
hmm well i don't have any 3rd party RAM so its not that

ok just googled and found this:

seems to be a problem with itunes and/or OS X

good news is... it's not a hardware problem for us. bad news... who knows if/when it will be fixed.
but i can live w/o coverflow for now..
