Windows Vista security flaw discovered...already

I read an article on MSNBC this morning on a security flaw in Microsoft Windows Vista. I'm not surprised, but I am. I'm not surprised that a security flaw was discovered, but I am surprised it was done so quickly. This is the most secure operating system of all time, according to Microsoft anyway. I thought the confidence in that statement meant that it would take a good 6 months to find a flaw. Oh well...secuirity flaws in Windows, what else is new, right?
