iMac Freezing with iTunes 8.01 & OS X 10.5.5 Workaround
Hi All
Got the same problem with iTunes 8.01 freezing up my new 3 day old iMac, while looking through the iTunes store. I noticed that it only happens while viewing the items on the store that are using cover flow. After a number of attempts at looking at the store and my Mac just freezing, giving me no option but to hold down the power button, I then decided to try a few things.
Coming from the Windows platform I was used to crashes and hang ups. During these times I found having the task manager open to be a good thing as you could see what process or application was not responding and it gave you the ability to stop the troubled process or application. I thought I would apply this logic to my Mac and open up the activity monitor.
With the activity monitor open, I then ran iTunes 8.01, navigated to the same area on the store where it had crashed my mac. While browsing the store I kept an eye on the activity monitor, watching out for iTunes to stop responding.
However it didn't crash my Mac and it has not done so

Thinking this was a fluke I shut down activity monitor with a force quit and went back to iTunes and it crashed the Mac almost straight away. This left me no option again but to shutdown using the power button. On start up I opened activity monitor and then iTunes. I have now run like this for several hours with no crashes while in iTunes, as long as the activity monitor app is open.
Please give it a try and let me know how you guys get on. ps you can close the activity monitor so that its not on screen.
