EXCEL - when I click in a cell or in the formula bar, the page jumps down.

When I click in a cell or in the formula bar, the page jumps down.

I am not clicking on the border, so it's not that.

It doesn't happen in all documents... just some. I copied the info to a new doc and it didn't do it right away, then started happening.

Macros are off.

How can I make this stop happening?

Thanks!
