EA has just released a new patch for Battlefield 1942, updating the WW2 shooter to version 1.31. Here's what this patch takes care of

Network/Server Fixes - We fixed a crash in co-op mode when restarting the map - this crash was known to occur right after a map switch - We removed the default Remote Admin Password for servers - there was a default password in place that could be used as an exploit - We changed the object collision system to prevent exploits involving players hiding inside of objects - more widely known as the "Coral Sea" bug Client Fixes - We locked out an exploit to prevent users from seeing through walls. Sound Fixes - We modified several attributes of the sound system to provide better sound performance.
