undo button not functional?

[tastyratz]

I have performed operations on my map I wished to undo, but the undo button appears grayed out all the time? Should this be functional if I want to revert to a cells saved values, last entered value, etc?

I havent got an undo feature in there. Would need modify the software to track history of each cell change etc and put it in a queue. I can add it to an enhancement list at this stage but it is not supported functionality currently
