I run v1.9 of tribes and I have no problems (running W2K Server build 2195)... that sounds like a problem that everybody had with earlier versions of tribes... from v1.0 to like 1.3 or so, whenever I would refresh the server list the program would lag pretty bad... if your running an older version of tribes try upgrading to a newer version... if your running v1.9 and it still happens, then I donno WTF it is ;P
