As an avid taker of notes for years on the Mac and now on the PC - you seem to have rather shifted your approach to saving user notes in 10.3.3.
I have always made a habit of using the 'control s' keystroke to regularly save my notes. (With the windows version still 'developing' this has become all the more important as crashes are fairly common). I see as of 10.3.3 that when I ctrl s - it closes the edit window.
Can this feature be disabled or controlled in some way or is this actually a bug?
