I have recently upgraded from ubuntu 11.10 to ubuntu 12.04. Generally in unity if we open several interface of an application then we can switch them by double clicking the icon of the application on unity panel. It shows the opened application's multiple interface in scale mode.
But ubuntu 12.04 does not show the windows of different workspace in scale mode. If i open three nautilus, two in same and one in different workspace then click on icon show two interface (which workspace contains two). That's means it only shows current workspace's application's interface.
Is it a bug or feature of ubuntu 12.04? Is there any way to fix it?
