The new note functionality introduced in Writer with release 3 is very useful
and easy to use. 
However in the indicated release candidate of 3.3 I found a problem I think was
not present in previous releases:
After insetting a note, the "post-it" space for it appears of the right side of
the page, and you can click on it and write your note.
However, when you're finished with it and you want tot move somewhere else in
your document, this is now impossible unless you actively click back on normal
text. If you leave the blinking cursor in the note, any attempt to navigate the
document using the vertical scroll bar fails.
I never noticed such a behavior before with 3 or 3.1 - and I have used notes
quite extensively. At first I feared some program instability, only after a few
seconds I realized that clicking back onto the normal text would allow me to
move around again.
Maybe this has been introduced to pursue absolutely coherent behavior of the UI,
in the sense that if you're editing the note you shouldn't go anywhere else? If
this is the case, I actually find it a bit too stiff. Having to click back on
the text each time you finish editing a note just to navigate the document is a
real bore, even if on the long run you would get used to it.
Thanks for the attention.
