Can't view pdfs except in full screen mode on MacBook Air

[Cocoonfxglen]

All of a sudden I can't view any pdf on my MacBook Air. I've tried opening the file in all the usual different ways. There's no real indication the file has opened other than when I click view in full-screen by chance then you can view the file. Which isn't much help when I need to prepare the file.

I done uninstall/reinstall using the Acrobat uninstaller. Turned it of and on again, all the usual tricks and still nothing. Doesn't appear to be any recent upgrades to the OS system. I'm a bit lost. Any ideas?

Try using Tile options from the Window menu.

And it is as easy as that, thanks. Out of curiosity, any ideas what needs to be selected in order for it happen in the first place?

Could be switching monitors, so that Acrobat remembers a position that is now off screen. Otherwise, random glitches to your preferences seem to happen a lot.
