dual screen in OpenSolaris 2009.06 ( Build 111b )

In the dual screen mode of OpenSolaris - Build 111b ( attached an external display on the laptop ) , the bar's on top and bottom of the screen do not extend over both
monitors anymore, like before.

Maximizing a window increases the size over both monitors.

Dialogs appear on one screen and not in the middle between the two screens, but not
all dialogs.
e.g. editing the menu with the right mouse button on the application button and
selecting the properties for an entry, shows the properties window in the middle
of both screens, having the the screenframes separating the dialog window.
