In any existing or new worksheet, if I am in cell A1 and I hit the tab key, I jump to cell P1 (the first cell on the next "page"). If I adjust the screen size to 50% so that there are more columns, it would then jump from A1 to cell AE1 which is now the first cell on the next page.

I have tried closing execel, restarting my pc, and cleaning the keyboard to make sure no keys are stuck down (like alt, ctrl, etc...)

Any thoughts?

Thanks,
Jason
