Have a very strange issue with iCal, and it has survived a clean install as well (I did get my stuff back with Time Machine though). Basically, when creating an event in iCal, I want to email invites to attendees. Now, the problem is that when I start typing the email address in, let's say I want to type in "email@example.com", as soon as I type in the second character, the first one will be overwritten with an "a", i.e. it will become "firstname.lastname@example.org". Then I have to go back, delete the character and put a new one in. This happens every time. Why?
