Thanks for that - I actually noticed it straight after I sent the email to you!
I now seem to have a more serious problem. I tried to purchase a song from the itunes store and it told me I needed to upgrade to itunes 7.5 to get that song. I upgraded but a notice popped up saying 'itunes requires MAC OS X 10.4.7...for more info on upgrading your computer....'
The problem is...now I can't get back to my old itunes, whenever I click on the icon on my desktop - the above notice pops up!.....
Have I lost it forever..??
