I just bought a new Sony Vaio VGN-SZ645, xp, sp2. On an intermittent basis, the browser (IE6,7, or firefox) freezes when I try to load a new page. It happens every session and frequently. I can't figure out what "brings it back"...but after a few minutes and numerous retry's, I am back in business. It does it on every wireless network I have been on. I have tried installing a usb wireless adaptor and get the same problem. My ethernet connection works fine.
Frustrated.
