When using the sawfish window manager, if you add the GNotes applet to your task bar and then create a note, you will not be able to type anything into it. This only happens with sawfish -- enlightenment, window maker and twm all work properly with GNotes.
Additional note: it is accepting input if you *paste* text into the note, you just can't edit it directly (and can't delete either).
Still a problem with RC2.
Seems to be fixed in current rawhide
