I've just recently reformatted my computer and reinstalled knight online and it runs fine. But if i alt tab to another program like msn, firefox or media player, and close the laptop lid and go afk, everytime i come back and try to alt tab back into knight online the screen is black. I can see the knight online mouse cursor, but nothing else but a black screen.
I didnt have this problem before the reformat, so i have no idea how to fix it.
Any help would be appreciated, thanks.
