Ican,t see the "call computer button" on the yahoo messenger chat window.This happens with one of my friend who is on my list and when he is on line. Even I can,t Buzz him. That is also disabled. The funny thing is that when he is off line then all these buttons are enabled. Can some one tell me is it my comuter or my chat freind has disabled all these things.I can talk to the rest of freinds who are on my messenger list.
