OK, a few too many exclamation marks but I have a very odd symptom on my 2010 MacBook air with 10.7.1 and safari 5.1. When typing on message boards or Facebook chat I can't use shift to capitalize the letter a. Nothing happens, using either shift. It only effects the letter a. QWERTZUIOPSDFGHJKLYXCVBNM all the others work see. And here is the really odd thing, caps lock works! As can be seen at the beginning of these two sentences. I've repaired permissions as that's about the limit of my techyness. It didn't help. In TexEdit, MSWORD, Pages and in fact every other app it works. So it must be something to do with Safari and my swiss german keyboard layout. nyone else have a similar problem?
