I have a very strange problem. When I go to a cell and right click and
select insert cell I get the dialog box that selects second option "shift
cells down" and it works correctly. But not again for 10 minutes? What I
get instead is dialog box with first option selected and when I select
second option "shift cells down" I get pop up box with error message "To
prevent possible loss of data etc,etc, etc." However after several very
long minutes it will work correctly once and then have to wait again??

Using Excel 2002
