Hey, hope this isn't too silly a question.. I installed msn messenger for mac, but whenever i open it the white disk box thing pops up on the desktop and it doesn't let me trash it while msn is open, only lets me "eject" it once i close msn. Is this normal, does this thing have to popup every time, and if so can i make it go away by itself when i close msn. I'm on tiger by the way..
