I'm using Ubuntu 12.04.2 LTS and Gnome Classic with two monitors.
The second monitor did't get any gnome-panel, so I added one there and added all the items that the first panel had, including indicator-applet-complete. So now I have two such indicators, one on each monitor.
Then, the notification of new messages from gm-notify gets inconsistent between the two: when I get a new message, only one of them highlights the envelope icon in blue.
Is it a known problem that others also suffer from? Is it a bug in indicator-applet-complete?
