Also here. It started two days ago, Nov 25. I could add to existing notes, create a new note but if I added text to an existing line, it wouldn't stay. Also, if I deleted text in an existing note, it wouldn't show. This happened on two computers where we updated to IE11 two weeks ago. However, one PC that had IE10 was working ok, so you are right that it is related to IE11. I downgraded to IE10 on the two PC's and Maximizer is working.It actually seems that the notes aren't being refreshed or properly displayed on the machines with IE11 because the changes did showup on the machine with IE10. Very strange.
