Comment 12 for bug 951929

I believe this problem is part of an even wider scope.

Unity seems to be having big problems with remembering which workspace an application is associated.

This is manifesting itself in one of three specific ways:

1) Applications not appearing in alt-tab. (usually combined with a hollow triangle on left, even if window is visible)

2) Applications appearing in dock as on the current workspace (solid triangle on left) but can't be brought to front by clicking on the icon.

3) In cases where 2) is the case, and the application is in alt-tab the menu bar doesn't alter for the application. Interaction with the application works so far as mouse clicking is concerned, but not for keyboard input, e.g. with Gedit I'm able to select and copy text but not get a live cursor in the window to alter it. It also means I can't click on any of the window resize buttons or get at the menu for the application forcing me to right click on the icon in the dash and quit from there.

The attached screenshot 'Dead Parrot' show this, with Polly being the stuck application. Even though title bar isn't shaded (application is forefront) it doesn't have the menu bar and I can't type within the application, even though all other mouse based interaction works.
