One thing that helps me is that I keep the sound on, especially when I am doing things like that. It helps so that if I am away from the computer, I can monitor when I get into the room. Also, if you have a friend that you play VMK with that you also chat with on messanger (I use Yahoo ) it is nice to know when you have actually DC since VMK might not always tell you. But if you get stuck on a number for a bit too long, you know what has probably happened.
Best of luck and keep trying for Host Games! You know that sometimes you win and win big!
