Since the last update I noticed that control-z (undo) takes lots more text away than in the previous version, and also than most regular text editors.
Type a whole sentence and do control-z and in most cases (if not all) the whole sentence disappears.
It's not a terrible thing but it is a bit annoying. I notice that I am using control-y (redo) more often these days (hell I even never needed to used that before). If not then I need to retype the whole sentence, or even bigger part of a whole post.
Jon, could you see if this is a bug? I think that in the previous version only one word was undone.
