I have two identical (at least as far as I can tell!) spreadsheets. One is a copy of the other that I use to test out stuff before turning it live. In the test one, one it is locked the arrow keys work moving the cursor around the unlocked cells as I would expect. However, in the live version, the heavy black border around the active cell disappears and the up/down arrow keys do not work. Running one of the macros causes the black border to re-appear but does not return up/down functionality. Help, I'm stumped!
