I have a lot of Excel sheets for all sorts of things - but none has ever acted up like this one here:
This used to be a totally normal Excel 2007 sheet which I was able to resize, maximize etc. - but not anymore. The MDI child window is fixed, both in position and size. I cannot move it around, more can I maximize it to use the full size of the screen anymore. I cannot double-click on it's title bar to maximize it either :-(
What happened? What can I do to "undo" whatever I did to it.
Any ideas? I tried to share / undo sharing, I tried to protect / unprotect the sheet - nothing seems to work...
