Hello, I was provided with a file and noticed that the "Undo" or "Redo"
functionality does not work, as I am used to.

For instance, on this inherited file, if I type a character in cell A1, as
long as the focus remains on cell A1, I am able to use the "undo" feature and
erase the typed charaters. But, after focus is removed from cell A1, the undo
and redo buttons become disabled.

Files that I create myself allow me to undo or redo steps regardless of the
cell to have focus, but for some reason, the inherited file acts differently.
Is there a setting Ican change to resolve this situation?

Any and All Help Will Be Appreciated - Thanks In Advance
