Every time I go to enter an email address when composing an email within Mail, the app crashes. I have tried deleting preferences etc, but it still happens. Im running Lion BTW, however it used to happen in SL (I was hoping the upgrade to Lion was going to fi it). Any ideas? As Im sure you can appreciate its highly frustrating. *Update* It seems to do it when searching it starts to search for an address that matches what you are typing.
