StarCraft 2 Patch 1.2.1

General

• Matchmaking has been updated to better match players queuing with pre-made teams in 2v2, 3v3, and 4v4 brackets.

Bug Fixes

• General
  - Fixed an issue where the title of a conversation window was scaling rather than truncating.
  - Fixed an issue where the Match History score screen was displaying "Null" for the map info for all games played before Patch 1.2.
  - Fixed an issue that would sometimes cause players to be improperly disconnected from a game.
  - (Mac) Fixed an issue that would cause the Control key to become stuck when holding Control and minimizing the game window, then going back to the game window and attempting to use Control+1 to create a control group.
