Messages Screen Sharing Ends with a "Hanging" Desktop Screen

Question

Since the OS X 10.8.1 update, Messages screen sharing – that used to work well in my environment – everytime ends up with a hanging desktop screen. That means: The screen of the desktop, where Messages screen sharing took place, freezes. I have to swipe to another desktop in order to successfully quit Messages via the dock context menu. After that, its desktop screen is responsive again.
This happens independant of who ends the screen sharing session.
It used to work seemlessly before OS X 10.8.1. So I think there is an issue with this update, Messages and the screens (desktops) management.

Hi,
As Screen Sharing does tend to involve a change from the Shared Screen at one resolution changing to your screen at possibly another (which for some produces the White Screen In Sharing) I thought it might pay to look at the method when wanting to go back to your own screen during a Screen Sharing Chat
I would still report it here

Obviously you have to use some of the free text area to state your OS version and Messages version at it will not appears in any of the drop downs.
