I am getting funny results using grouping in NSUndoManager.
If I begin a group on mouse down, and end the group on mouse up, even if I do nothing in between, it seems to record an undo task, with the plain name "Undo" in the menu, dirtying the document. The "task" is null - it doesn't actually undo anything.

What does your undo manager's -(BOOL)groupsByEvent method say? Default is YES, so for each event a group is open and closed. You didn't mention calling -setGroupsByEvent: so I assume it is left to the default value?
