Twinview..moving between desktops [PROBLEM]

[MetalWarrior]

Hi,
I've just been able to make twinview working on my gentoo box in clone mode, which I needed, but I have a question about the other modes (es: RightOf): when using that modes I can no move the mouse from the primary to the secondary screen.. for example, if the secondary screen is on the right, when I move the mouse on the right extent of the primary screen I see the cursor on the left extent of the secondary screen, but I'm not able to go and do any action on the secondary screen.. I'm using XGL, so I don't know if it is an XGL-related problem (this is why I asked here instead of in the "Unsupported Software" section)

Any idea?
