D2P runs twice after reboot.

[GronbergInfo]

Hi, it seems that i have this one installed twice, but yet not..

When i install the extension, i get what i dont, the dash is replaced by the panel as i want it.
But next time i reboot i get both the dash and the panel on top of each others.
Going to the extension page and press the X, removes the extension, and the dash is back.
If i now go back to the extension page, and install it again, i get only the panel, until the next reboot, then its doubled again.

How can i purge or something it all, so i can perhaps do it "fresh" and only get one "taskbar" (panel) running at reboot?
