All programs (incl Internet) appear twice in the bottom panel, once you close one tab, both close. How can I get this fixed? Thanx a lot in advance
You got a dupe panel.
Just means its being displayed twice. So... easiest way is to delete the panel and make a new one, use the alt combo (I think its alt... might be control)
So after you delete it, make a new one. Combo the desktop and click "Add panel"
If you got dual monitors, however, there might be another reason... but on 11.10, iunno.
