Well it looks like I may have cracked it. I did some searching on the Internet and came across DRTCP. I downloaded the program and ran it. It came up with some suggestions for tweaking the system. The main one was to increase the TCP receive Window which I have done. The result is I've actually got to 3.omb o the desktop so have exceeded 1.8mb for the first time. Will do other checks in the morning and see what I get. regards
