I'm using MBA w/ external montitor and have both screens active. Opening the Pages app (ver 4.3) and using it on the external screen is ok. But when I try to go full screen (ctrl+cmd+F) on the external monitor the app is just "magically" drawn from the external screen and switches to full screen mode on the laptop screen?! Neither Keynote or Numbers do this = those apps can go full screen mode on the external monitor. Cannot see any specific setting for this. Any hints appreciated. Thanks!
