Dear Friend,
Thanks. Yep, the lastest version of QQ program requires 10.6 or later...but older versions do not.
One of my friend is using 10.4.11 system, while he is able to login with an qq for mac 1.0 beta (606) version.
I downloaded the same version, and successfully installed it, same problem occurs, saying "login timeout"...
I thinks there is something wrong with my mac, as I cant sign in Windows Messenger, either. A message promoted saying "Sign in to Window Messenger failed because the service is not available or you might not connect to the internet."
However, it is fine with Skype...
So wierd....
