Hi!  I have used Aperture 3 for many years and have never had this problem.    I work with two monitors - my MacBook Pro and an external Apple monitor.   When using the external monitor, it becomes my main display for editing photos and the MPB is used for email and other programs.


Suddenly, when I open Aperture, it automatically wants to use the secondary display, too.   Any photo that I enlarge in the main display will appear in full-screen mode in the secondary display.     I don't want this!   I want the secondary display for other tasks.   This is not a mirror of the main monitor.


Is there a way to undo this feature?   Did I accidentally hit a key that created this problem?


Thank you!
