I have a 1080p LCD HDTV and it suffers slightly from "Image persistence" It's not permanent and I've taken preventative measures to minimize the effects and the effects have been reduced a lot in the past 36+ hrs since I noticed it. Anyway, I have my Taskbar set to Auto-hide, but I noticed after installing Nod32 4.0 it keeps flashing from Auto-hide. It happens very quickly, a split second, and frequently and it's quite annoying. I tried disabling Alerts/Notifications, and even program animations, but it persists. I installed Nod32 4.0 twice and it only happens when it's installed. It wasn't a problem with version 3.xx. I know this seems like a pretty obscure and unimportant problem, but I thought I'd share anyway.
