I too have this problem, SGB being the worst but also problems with Chartbuster and Sound Choice as well. SGB and CB don't refresh their screens so the crap just builds up untill some times the screen is unreadable, SC refreshes after every page so the problem doesn't get that noticeable/annoying. I use Plextors, one MTU certified the other not.Same problem with both. I've tried using a copy from Microstudio, sometimes it improves things, sometimes it gets worse. finally decided it was the cheap media these brands use.
No solution except not to buy SGB or CB anymore. If you find a solution I'd love to hear it.
