iTunes problem - iPod doesn't show?

Question

iTunes on my computer doesn't seem to recognise my iPod. It must be the software rather than my hardware because if I go to another computer also with iTunes 7 it works perfectly. Also, the iPod shows up on My Computer. I've done everything on the apple website (what they call the 5 rs) including uninstalling and reinstalling the software, resetting and restoring my ipod etc. Very occasionally, if I restart the computer or go into "Manage - Services" and restart the iPod service, the ipod will show.
When I uninstalled I was sure to get rid of everything, delete the folders in program files and then delete the recycle bin. However, it seems there must be something I have missed if this software problem is persisiting - maybe in the registry? Maybe someone here can help me delete it all from there?
I also wonder whether it's something to do with the computer thinking it's a drive because it automatically opens the files on the iPod in an explorer window. I tried changing the letter.

Thanks for the reply below - I can't revert to iTunes 6 because iTunes 7 has updated all my music and it can't be read by iTunes 6 any more! I already tried this. As I said, it all works perfectly on another computer, so does anyone have any other suggestions?

Answer 1

Apple fixed lots of bugs in iTunes 7 with their latest release, iTunes 7.0.1:

"iTunes 7.0.1 addresses stability and performance issues with Cover Flow, CD importing, iPod syncing, and more."

This update is meant to fix all the problems iTunes 7 created :-S

Answer 2

Revert to iTunes 6 for now, it's a known problem with 7 - I'm sure mac will fix it soon with a patch, but for now, just uninstall 7 and re-install 6.
