Address Book missing from Running Applications
I run Address Book and "Open at Login". I'm running MacOS X Lion 10.7.4 and Address Book 6.1.2 on a MacBook Pro. I have just recently noticed that though the Dock shows the little blue indicator that Address Book is running and the Ctrl-TAB shows that Address Book is running, there is no way to bring up Address Book's Window. This started about a week or so ago.
Activity Monitor window also does not show the Address Book in the processes list regardless of the filtering.
Is there a new bug in Address Book?
