Hi people... I hav a P4 2.93 GHz System running Windows XP media centre edition... I use yahoo messenger 7... The problem is, I'm not able to use my web cam in it... Whenever I try to start my webcam, it says that some kind of windows Firewall is preventin the Yahoo messenger to use it... I have checked it out in the controlpanel>security centre> firewall in windows and tried disabling the firewall protection for Yahoo! messenger... But the problem still persists... Help me guys...!!!
