Chat windows are being attracted from other VDs in an evil way
If I open a chat window on VD No.5 and leave it there open/minimized, then switch to VD No.1 and someone else sends me a message, the chat window from VD No.5 is being moved to the current VD and the new message opens in another tab. If I leave a window somewhere, I want it to be there and this is how every application behaves. Chats with new contacts have to appear in new windows, in case there is no chat window open in the current desktop. I consider this of "major" severity.
VD = Virtual Desktop
