Cells stay highlighted, cannot use mouse

When I click on a cell in excel, that cell shows as clicked on, but when I move the mouse all surrounding cells become highlighted as well. So I cannot input anything anywhere, as moving the mouse around just keeps highlighting cells. And I cannot shut excel down as trying to move the mouse to a menu bar keeps highlighting cells in the worksheet. The only way to get out of excel is to End Task. I have come across this problem before, but I don't know how I inadvertently activate it, and to stop it was some combined of Ctrl-Enter but I can't remember what. Hopefully someone will understand this and be able to assist me. Thank you!
 
Hi
you have probably invoked the 'extended selection'. Check if there is
an 'EXT' in the statusbar. To switch back hit the F8 key
 
Hi Frank,

No EXT showing, but I can see how to switch it on and off via F8 (thanks for that tip!). I have the same problem in any file I open or any new file. I have tried another mouse, and that does not seem to be the problem. The arrow keys etc no longer work when this happens. If I start to type in Cell 1A as soon as I open a file, I can do this, but as soon as I use the mouse it starts highlighting everything again. Any other ideas?
