Well OK so you think it is a problem with L/W I do not think this is the case. I run L/W on 3 diffrent computers and it works fine on all 3 it uses between 3% & 5% of my cpu and 40,000k & 60,000k mem depending on how much UL & DL are going on weather I am in ultrapper moed etc, all are running L/W 4.9 and the latest java In the previous post I made a mistake on Ghz cpu is running

As you can se there is quite a bit of diffrence in these 3 machines but they all preforme fine with L/W running I am able to play games cruse the net or do whatever. I do notice a slight decline in the laptop but not much. So you can blamb L/W if you wish butt I think you are wrong. All the above machines are running XP Pro
