No. Fast and imprecise scrolling doesn't improve anything either here. I'm surprised how people get improved behavior from these. But I agree with Stefan to shut up here from now on. I don't have the time to conduct an in-depth analysis of this problem and spotting a possible culprit without such an analysis is, in fact, futile. martin
