Caveats #

Please beware that anytime a cell is highlighted you will lose your Edit history (Undo / Redo arrows).

Best way to avoid any unintentional loss of history is to keep at least 2 cells as the Minimum cell limit. This will allow you to have better control of what gets highlighted without the need to keep turning highlighting On and Off.

This is not a bug but a feature of Excel. Anytime any Add-In changes anything the Edit history is cleared.

  • Excel 2007
