Hey guys, I had been trying to find a fix for the freezing for a few days now, When suddenly it hit me: The game had been freezing the keyboard and mouse, Yet things were working in the background. What if i tried the game in window mode? Well, I did a little snooping and found a program called "Chaos luanche
r". I used it to play starcraft in windowed mode, And what do ya know; Problem solved! I have successfully played both on and offline for hours on end with no problems, Not even the strange discoloration! Give it a shot!
