I'm using the following components in Xubuntu 11.10:
AWN (0.4.1) DockbarX (0.48) awn-applet-dockbarx (0.48)
I activated the "DockbarX previews" in the "DockbarX Preferences". However the previews are always empty. This means that the space which is reserved for the preview windows is showing up on mouse over but it's empty and I can only see the underlying window or desktop.
Thanks in advance!
