I have Skype and yesterday I was chatting to my friend in Portugal and then she started to not be able 2 hear me but i can hear her. This happens on my MacBook and my PowerBook. What gives? Thanks.
Don't think its your Mac. Happens to me sometimes too... on my work PC it used to sign in and out all the time but I think that had something to do with the firewall or some other such gubbins. Skype can be a bit temprimental some times in my experiance.
