Hi,
I also experience this before. I do not know exactly why but ending the
application is the only choice. May be you have to check the keyboard Ctrl
key. Sometimes it stucks..

Hello All,

I have a user who is experiencing this problem in Excel. When she types in a
cell & clicks in the next cell, her mouse goes into highlight mode and she
can not disengage the mouse to use anyother part of Excel. She then has to
end the Excel application. This does not happen in anyother MS application.
