Acrobat Reader - This is making me nuts...

[Rigger PJ]

I have a PDF file on a network that is set to open Full Screen.  On three computers, it opens to full screen just fine.  On computer #4, it will not open to full screen.  All other files on the network open to full screen with that computer, but that particular file will not. It opens with the tool bar open on the right side.

Any ideas?

Thanks
