I've got a Logitech webcam which works fine with AOL and MSN Messenger and also fine on it's own. I recently added Yahoo Messenger and got an error message about being behind a firewall and not being able to use the cam. I am running XP and McAfee Personal Firewall but I followed directions for both (as best I could) and added or opened ports and made it as far as getting a picture on the cam in Yahoo but it now gives me an error about not being able to connect to the (Yahoo) network. Can you walk me through the appropriate steps and settings to make my webcam function in Yahoo Messenger. HELP!
