If you are running the latest version of Xfire on XP Pro 64bit you may experence freezing when you move your mouse. If so this is not a Guild Wars or any other game error. The issue is currently being researched; here is the thread: http://www.xfire.com/xf/modules.php?...9757#1 549757
A quick fix is to shutdown xfire64.exe Process in Windows Task Manager.
If you can, please send in the log files! Instructions can be found in the second post to the thread.
