I have got this weird things happening. A folder call "Boot OS X" will suddenly appear on my desktop, screenshot as follow: When double click on it, it does not open. When I reboot my Mac, it disappears. Sometimes, I can get a few of those folders on my desktop until I reboot. Been searching the forum without much information. Anyone can shed some light on this behavior? I am on Snow Leopard, and this started before I upgrade to Snow Leopard.
