Cronic, do you happen to be running it in 800x600 resolution (not for windows, the one in the video options on the diablo 2 game menu)? If so, I might know something about it. After playing it in 800x600 for a couple hours, it starts to leak memory somehow, because I got 320 RAM, but it says 5-20 Skip even though it doesn't say Phys:320/320, it usually is at 200/320 in 800x600, plus randomly the 80% of the screen becomes black, but is solved by rejoining/making a game, otherwise restart your comp.
