This is all assuming that your problem is that your toolbars are blocking your access. I can’t actually get my document windows to go off my screen entirely…
Go up to the “Window” menu and select “Zoom Window”. That should bring the window back down to where you can grab the top bar. At least, it just worked for me in Word and Excel.
You can also close whatever toolbars are blocking your access to the document’s top bar, then go through View > Toolbars to get them back.
A third option is to use the “resize” square in the bottom right-hand corner of your document window to widen the window until you can get to the top bar. That works if your toolbars don’t extend across the entire width of your screen.
Probably not, since earlier versions of MacOS “Classic” would only let you grab the title bar as well. The “grab any side and drag it” didn’t really come along until the Mac’s “Copland” interface, IIRC.
I am so happy I found this thread. Losing the document above the screen has happened several times over the past year. Sometimes a restart would help; sometimes not. However, Fn9 worked immediately. Thank you. Thank you. Thank you.
