vista: closing game to tray

[zwr]

When i close the game window to the tray the playerlist stops "working". For example with the game closed i am unable to expand servers on the 3rd tab (they finally appear when i open the game window again).

Another very! important thing is that with the game window open i can idle indefinitely on the login server but with it closed to the tray it just dies after a while (15 min. or so)
