Hi all

I have a current problem with itunes on my imac (24" 10.5.8)
Recently itunes (10.2.1) has started flickering when playing.
showing mixtures of screens, ie a combination of what is playing, itunes store, other songs, all mixed up, random images and texts not related, then flickers again.
Sound playback is fine.
This started a few weeks ago, i downloaded 10.2.1 and still same issue.
No other software is doing this.

Can anyone suggest a way of sorting this please?

Many thanks
