Who knows how long the Counter-Strike 'hit box' problems have been around, seems like forever. But they are finally fixing it! Counter-Strike.net has a server side patch to fix the "invincible legs" bug.

We've released a 1.1c Server Side only patch for server admins to grab and install. This is mainly a fix for the "invincible legs" bug when using certain weapons. There are a few lingering hitbox issues that will have to be addressed in a client side patch or upgrade (probably 1.2).

Additionally a the same thread on ShackES that I spotted the word on the new Counter-Strike describes another bug that you're able to flashbang everyone on the map from a single spot. Doh. Instead of discreetly notifying the CS team of the bug though XSR felt it was necessary to post a demo demonstrating for everyone how to take advantage of the exploit. (yes I realize Maarten mentioned this yesterday but I thought it was a bigger deal)
