About the engine.exe, probably the problem is linked a to some particular setting of my PC, so no happen over any machine, and for a expert user it is not a problem (I stop the process from tasks manager) but for a novice can be hard understand why the CPU continue to run.
I think also the possibility to set manually the IP to use with multiplayer game is a important modification to do.
THe game function with directplay? it is NAT-friendly (

)?
