I recently re-install Ubuntu 14.04 and ran all the updates it asked for.
After adding the sticky-notes to the menu bar,from the "add to pannel" options, any note that I put on the desktop is not saved when I log out or reboot.
I did save the ~/gnome2/stickynotes-applet file from the previous install, and was hoping to put it back on this one, but there is no gnome2 directory.
I have also noticed that the previous version is 3.8.1 and the current version is 3.5.92.
Side note if it helps, I am using gnome-session-fallback, which I also used on the previous install. I just don't like Unity.
