PAL TALK IS EXCLUDING & FRUSTERATING MAC USERS

I have a green nick and can only pull up 4 cams at a time. kind of frustrating when yesterday i could! Very frustrating!! I will not be renewing my nick if i cant use the program on my mac. A whole demographic is being left out becuase there is not a functioning interface for Mac's. The issue needs fixed whether it be a mac program or the express just gets fixed!!
