I know these things won't affect gameplay, but

First screenshot - In the Deathmatch screen, if I begin a game with 4 CPU opponents, a scrollbar appears on the teams list. (I guess this can be solved by making the list control 1px taller)

Second screenshot - The two pictures' (LAN and WormNET button) black pixels are transparent, so that the background stars are still visible underneath them. These buttons should be opaque, shouldn't they?
