Thanks. Never new that button existed.
I opened up Excel and tried to move across cells with the arrow keys. Instead, the page scrolled as if I was hitting the scroll bar with mouse. The active cell did not move, it would just scroll off the page.
Enter and tab still work to move the cell down/to the right, respectively (and shift enter moves up). When I go into a cell and try to enter a formula, it still scrolls instead of moving to the reference cell when pressing the arrow keys (but I can select the cell with the mouse).
I played with the options but there was nothing that I could find.
Has anyone experienced this before?
Any advice would be appreciated.
