Excel selects multiple cells when I click on any single cell.

Hi everyone, I'm wondering if this is something anyone else has come across.
As mentioned in title: Excel selects multiple cells when I click on any single cell. I am unsure if this may be a graphics card compatibility thing or and excel issue?
It only seems to happen in "Page Layout View"

As my question suggests, I'm aware of this.
In my case however, it isn't an option. I have images in the header that don't appear in normal view, plus I like page layout view better.
I'm thinking on contacting NVIDIA to find out what they know.

Yep you're right there, I've been doing this for quite some time now. It wears thin believe me.
I will be getting to the bottom of this before it sends me crazy.

I have several sheets on one spreadsheet. It only seems to happen on one of them. It doesn't happen on a brand new sheet or old sheets. Is this the case for you?
Its almost like some type of corruption. There must be some difference between this sheet and the others. At least its a start.

Ok..... New revelation........ I have found that if I click at the top half of the cell it only selects one cell. If I click my mouse half way down the cell or lower it selects the one below.
This has to mean something to somebody? Maybe a link to formatting or something? Will keep you posted!

It was a reworked file from 2007 but so were other sheets that aren't doing it.
Unfortunately for me there's way too much work in starting from scratch with macros on other worksheets and such.
