Hi,
I raise this problem in old discussion but recently I see a video without my problem so I decide to ask again. My taskbar pager shows windows only on actual desktop and when I change to another one it clear the previous mini-desktop.

Other issue, since the last update when I change desktop using taskbar pager, it copies the focused window of previous desktop on new one. To restore I move the copied window to its source desktop.

I use win 7 64.
