Comment 17 for bug 90261

Confirming this as well. Am on Xubuntu Gutsy Upgrade with compiz-fusion. Every Xubuntu Distro I have used before since Dapper have had this problem at some point. I was hoping this recurring problem would be solved already in Gutsy but its still here. :P

Killing/restarting xfce4-panel and adding the control worked a few times but now it refuses to be added again. Dragging the control to the panel seems to work as of the moment.
