Is there a quick was to find out if something has changed in the contents of a sheet?
Ideally, I would like an event 'Something Changed in Sheet', which I can use to, for example, highlight a 'save' control.
Really slow way would be to keep the contents of all cells, paint them, then respond, for each cell, to an event, compare the 'was' and 'is' values, and generate another event if they are different.
Before I do this, I'd just like to check that there isn't a simple way which I can't find.
Thanks
