I recently upgraded to Leopard. I am not sure if that is the source of my problems. It didn't start until after installation and I was using Mail before. When I am working in Mail some pretty funky things are happening. When I type the first letters of the first address everything is cool. Then when typing the first few letter of the second name it comes out like this:kkakatkate. (What I am trying to type is 'kate') Now I have discovered that it is doing the same thing in Address Book!

Has anyone had this problem?!
