This has been going on at least 3 months with the browser. The back arrow will disappear, sometimes the text completely disappears, sometimes you can see it but its unreadable, looks like the letters are missing pixels. Sometimes the images get corrupted with black pixelation. If you quit and restart it goes away, for a while. The problem seems to be affecting my online games as well. I play "Steampunk Tower" on Yahoo!'s free game tab and it always crashes my machine hard, as in abruptly shuts down the system with no warning. This is not the only game to be affected. I have both McAfee and Norton 360 and they find nothing when I scan, but they can only detect what they know about so I'm looking for something new and unreported. Or maybe an update failed or has corrupted a file, I don't know. I do know that its very irritating and I'd like to fix it, if possible.
