as an FYI, last night this wasn't a good idea:
The following packages will be upgraded: gir1.2-matepanelapplet-4.0 (1.27.1-2+b2 => 1.27.1-3) libmate-panel-applet-4-1 (1.27.1-2+b2 => 1.27.1-3) libmate-panel-applet-dev (1.27.1-2+b2 => 1.27.1-3) mate-panel (1.27.1-2+b2 => 1.27.1-3) mate-panel-common (1.27.1-2 => 1.27.1-3) this morning downgraded to previous version and all is back to working. held this update for now... songbird
