StarCraft 2 Freeze on exit bug
StarCraft 2 Freezes on exit
Many users have reported that they are experiencing lockups and various crashes in the StarCraft 2 beta.
Most of which are not game breaking, such as the game exit crash.
If Starcraft 2 crashes when exiting or quitting the game, a temporary, but very simple solution to fix the crash is to log out of StarCraft 2 before quitting the game.
We are aware of an issue that causes crashes upon exiting both the StarCraft II beta client and the Map Editor. This will be addressed in an upcoming patch.
I must give Blizzard credit though, for a beta version, StarCraft 2 is incredibly polished and relatively bug free when compared to many other, released titles.
