I've encountered a strange problem with LNS 2.04 P2. I have a P4 3.06 GHZ processor and when I have Hyper-Threading enabled, when I surf with IE 6, it will sometomes lock-up my processor at 100% in Task Manager, with IE using 50% and System using 50%, and I can't end the IE process in Task Manager... with HT disabled no problem exists. When the problem happens, IE 6 remains in the Connected Applications panel in LNS even after I exit the browser, but no outgoing connection is shown in the Log function, Using Port Explorer 1.62, when the problem happens and I exit IE 6, all the connections that IE 6 was using show as Listening, but never close no matter how long I wait. This usually happens at sites with video/Flash content, but sometimes as soon as I start IE 6 it happens. After quite a bit of trouble shooting, I uninstalled LNS and tried Sygate 5.0... the problem does not happen when using Sygate, I also tried Outpost and it works OK as well. I don't have this problem using Netscape 7.02, just IE 6 and the only way to clear it is to reboot. Does anyone have any idea what could be causing this? It seems that at some very basic level in Win XP SP 1, there is a system resource conflict with LNS and IE 6.
