For some reason in the past few days I can't delete text after selecting text
and pressing the "backspace" button or selecting text and then typing other
text which usually replaces the selected text.

I'm not sure if I accidentally entered a command or if this is the result of
an Automatic Office Update, but I really want it back the way it was!!

Thanks for any suggestions.
