Issues - ghost data
 

I am having ghost data appear randomly in my workbook while trying to clear
data. The workbooks are large and contain multiple macros. When clearing a
feild, Other ghost-like images of cells and data pop-up randomly and clutter
my view. This is a new computer running windows 7 and excel 2007. IT has
already updated my video driver and we are all stumped.

Please respond quickly with ideas...they are threatening to give me back my
old computer....
