Favorites doesn't work

How do those clowns at MS do it!!!
Upgraded to Win 7 now my IE 8 will not allow me add to my favorites.
Can't they ever get it right?
Anyone got any ideas what this problem is?

You could use this Tutorial and see whether it fixes:

Thanks for the update and advice. I managed to get hold of MS support and they couldn't fix it either and after about 40 minutes with them the phone line went dead.......
The problem wasn't fixed.
I poked around in IE tools etc and I don't know what I did but somehow it now works.
