I am running Adobe Acrobat XI Pro on my Windows 7 computer (resolution 1920 x 1200). All of a sudden the toolbars and dialogue boxes (in Adobe only, not other programs) are about twice normal size. The toolbars fill too much of the screen, and the dialogue boxes don't fit on the screen (requiring me to scroll down for the "print" button, for example). Everything else works fine. I have no idea how this happened or how to fix it. Please help.
