Excel selects multiple cells instead of one (cells are not merged) - When clicking on a cell, Excel will select multiple cells around the intended selection. Also, the number of cells automatically selected and position of the selection is random each time the intended cell is clicked on.
Shift + Arrow Keys will select correctly but is not practical to use every time.

Might be EXT mode - touch F8 to clear this
Might be Sticky Keys - touch SHFT 5 times to clear this

To expand on EXT mode: Regarding EXT mode this is turned on or off in 2007 by pressing F8. It is also called Extend Selection in 2007 or later and if the Selection Mode option has been turned on for Excel's status bar you will see "Extend Selection" displayed. This mode can also be turned off by pressing Esc.

It's still a bug in 2010. When at 100% zoom, it auto-selects 4 cells for me. When a 115% or 85% it works fine.
I see this is from almost 7 years ago but THANK YOOOOUUUUUU
I fixed this with zoom. I zoomed in then out and it fixed it.
