iMac Finder dies…

Since I updated to the latest versions of Quicktime, iMove etc. yesterday the Finder on my iMac is repeatedly crashing. This includes the icons in the top right hand corner of the screen disappearing and then reappearing every 15 seconds.

Other applications crash when launched at well.

I managed to stop the Finder window crashing by moving from using Coverflow to the standard directory listings but the icons at the top right still crash and the machine is unusable! Firefox and Safari seem unaffected.

Any ideas of how to solve this would be gratefully received!

Lets see what the chances are of a blog request for help are; all the “A Listers” (a.k.a. Scoble) say this is the future of support and recommendations. How does it work for the rest of us?
