KDE apps on Xfce 'stick' to the one desktop workspace.
I have a pretty obscure problem here. I'm running Slackware 10.2 using Xfce 4.2.2. When I open a KDE application like amaroK, it appears on desktop workspace number 4 (of 4). That's fine, I move it to my primary desktop workspace and minimise it to a taskbar icon.
But every time I click on the taskbar icon to restore the program, it moves itself back to desktop 4! I thought it might be a feature in KDE or Xfce. I tried to find some kind of config option in KDE but with no success. Xfce doesn't seem to have any 'sticky desktop' option either. I have no idea.
As always, any help is greatly appreciated.
