I am running Excel 2003 from Office 2003 Professional When I initially go
into the program, I have full mouse functionality (ie clicking on menus,
the
sidebar, etc.), but as soon as I click on a cell, I lose it. When I click
on
a cell, all of the sudden, the program acts like I have not released the
mouse button and highlights all the cells the pointer runs over and it
won't
free up until i close the programme. Can anybody help me please?
