Hi

Suppose you have some unsaved text on SciNotes. Then you close the main
window of Scilab by typing "exit" or by pressing [x] button on the window.
You'll see a message box popped up by SciNotes saying " 
<filename> has been modified since last save save it?" Now when you press
"Cancel" button, this cancellation is ignored. Scilab closes SciNote and
itself anyway. Unsaved text is lost.

I think this behavior upsets users, and would like to see it fixed.

Scilab 5.3.3 (32bit) on Windows 7 64bit.
