I have a secondary connection and yes this symptom occurs on pretty much all functions with the computer,such as scrolling is not posssible for an interval,even typing, the display of letters can be delayed, then suddenly they appear all at once. I have also noticed that most people have trouble uploading. Most of the time if they do connect, the speed is very slow and usually stops after a while then disconnects.
I'm not sure what patch I have although the toolbar indicates "patch operational". Unfortunately for me, I fell prey to a pay to get winmx back after enjoying it for a couple of years before the crash- I was unaware that it was available free. As far as Peerguardian or PGLite, I do not know. I hope you can help restore the service as it was. Thanks for your time.
