So far so good.
Let me describe some of the problems encountered before this.
I was playing a SP campaign I think it was created by you "The GDI Airforce", the mission "Get'em NOW!".
The problem I have after playing the mission for quite some time
(i)when I clicked "ESC" to save it for later, it went into the Menu page but the cursor was stuck. I was then forced to click "ESC" to go back to the game.
(ii) Ramdon crashes when when I move the cursor.
Anyway, I tried the same mission again, problem(i) did not appear, but problem(ii) still persist. Perhaps the problem is due to this map.
Anyway in CCconfig, I have ticked "Limit the Frame rate" and in the game control I have the Scroll Rate set to the 2nd lowest.
