An icon for Wingpanel keeps appearing on the plank. It happens right after startup and usually after I pull it out of suspend. Clicking on it doesn't appear to do anything and right clicking and selecting either close or keep in dock does not do anything. The only thing that seems to work is saying killall wingpanel in the terminal as this stops the wingpanel (and gets rid of the icon) and the wingpanel restarts without the icon in the plank. Is there a way to have this not happen? Also the bluetooth symbol keeps disappearing from the wingpanel but this is less important. However, it is also fixed by killall wingpanel.
