I have a computer that every Excel worksheet acts as if Extended Selection is
one. Once I click a cell it begins highlighting as I move around and I can't
get it to stop unless I close the program down. I have pressed F8 and can
turn the EXT on the status bar on and off but either way it does not work. It
only happens on one machine and if the file is brought up on another computer
it works fine. Is there a computer setting that effects extended selection?
