If you do a google of 'Yahoo preferecens' you'll find that several people are experiencing this same problem.  I'm getting it when clicking on a Yahoo news headline on my Yahoo home page.  It looks like the problem just started last night, and there doesn't appear to be any answers yet.  I'm getting the message from both IE7 and FireFox, both running under Vista.

 

By the spelling, and lack of period after 'Please try again', it would almost seem like this is some kind of hack, and not a legitimate message.

thanks. I did a full scan and found nothing.  also checked add/remove program, found nothing suspicious there either. please keep me posted if there is a solution.

From googling the error message “we were unable to save your preferecens” I found that others had solved the problem by deleting their entire IE browsing history – which I did, including checking the box “also delete files and settings stored by add-ons”.  The problem is now solved.  Hope this works for you, too.
