I can't see how having to move your mouse over the msn icon, and then having a display picture, msn main window, and 2 conversations windows pop up is any better.
And I have skype and msn open permanently, but very rarely use them, I really don't want them sat on my taskbar all the time.
EDIT. They're back in the tray icon, just had to change the compatibility to windows vista. Sooooo much better.
