Yeah... There used to be a way to force the resolution you wanted, but seems the game ignores the registry key now unless you buy it again...
Curiously, when games are made, are they hosted bnet side, or do users still have to forward ports and be actual hosts if they want to make a game that's non-ladder?
I actually logged into the game yesterday and joined an old Battle.net channel, what's funny is, when I am on a Bnet 1.0 game, I can see my SC account, but my SC account can't see my bnet 1.0 account LOL
