Hi Wesley,
Take a look at
http://www.mvps.org/dmcritchie/excel/mouse.txt

If you can predict that the problem will occur within 3-4
days could you try simply assigning the wheel mouse
button to Enter and see if it happens again soon. AND REPORT
back. If you don't want to experiment update your
mouse drivers. Nothing works for everybody, and nothing
works permanently but I've only had the problem once
in a couple of years now connected to PS/2 but the last
six months on USB so I could use a separate keyboard.

When I double click on the Excel spreadsheet, it opens with the default
"Book1" and cell A.1 is selected, and it seems as though the shift key is
being held down, even though it isn't because where ever I move my mouse it
just highlights cells from that point (A.1). I've seen this in two
different PC's now...both laptops, but one was using a mouse and the other
was using the touchpad. It doesn't happen all the time.
