A lot of people have been having problems with the Dell start page (I just tried it and couldn't edit anything either, though I'm using Firefox with XP). In another thread here supposedly Dell/Google were working on it, but there's really nothing you can do on your end to fix it. If a regular iGoogle page works, your PC is fine.
Thanks for the quick post to my question/problem. I finally figured out how to set-up my iGoogle page today. Now all I need to do is figure out how to be able to save my login and password for iGoogle when I delete cookies so I don't have to login every day.
