Taskbar in the wrong window

[Lars Behrens]

Hi there,

I'm using Xfce 4.2.0 with Xinerama on Slackware current  (xorg 6.8.2).
Unfortunately the taskbar shows up only on the left monitor.

In the taskbar settings dialog there's only the option of showing it on 
top or bottom. Is there a way to move it to the other monitor, just 
like the panel, which can be dragged from one monitor to the other?

TIA!
