I think this problem was fixed.

I also find that if I am in desktop 2 then I logout and the logon again, I will be in the desktop 1 but the icons are all wrong, they are from desktop 2.The only thing I can do is to press hotkey of reload icons from current profile.That's annoying.
I think it needs to be improved~

I set desktop4 for games and play full screen games there.
The bug is when I switch to the ,for example ,desktop1 directly(I mean by pressing alt+1),the full screen game or any other full screen programs will minimize to the taskbar in desktop1 and the icons in desktop4 will copy to the desktop1 wholly.no matter what desktop you switch to, the same problem it occurs .
But when I use the desktop switcher (default hotkey is win+w)to switch ,it works perfectly. Full screen programs just minimize to the taskbar in desktop4 only and icons in desktop4 won't appear in desktop1.
