Every time I click on my desktop to give it focus, my Windows Live Messenger goes into "Busy" mode. It stays in busy until I click on part of the Vista interface (start menu for instance) or another application..
I know that dreamscene and deskscapes are technically full screen applications that run through DirectX (I think anyway) so maybe that is what is confusing Windows Live Messenger. It does go to busy when you start a full-screen game for example. Who knows.
It could be any one of these causing the problem: Stardock Deskscapes 1.01, Windows Dreamscene Ultimate Extra, The Earth dream or Windows Live Messenger itself causing it. It could even be a combination of them all. Any ideas?
