[Hampshire] [OT] Mouse not selecting text in Word under Vist…

I have a user who has suddenly found he cannot select any text, or do
anything with the mouse in a word document. He can click on menus,
buttons etc, but not on the text. Every other application is fine,
including other office applications.

Some forum searching has suggested a workaround of running it as
administrator, but he seems not to have this option for office
programs.

Anti-virus etc is all up-to-date, and no problems reported.

Any ideas?
