I didn't post so far on this thread because like Peter I only rarely have noticed this. Typically, I noticed this only when the ADSL/wireless connection is congested or playing up. Essentially, I concluded that I am asking FF/Konqueror to scroll down a page that it hasn't yet finished downloading or rendering. Not sure if the latest version is behaving in this manner. I have not noticed Opera suffering from this, probably because it uses a different model for deciding at which point in the download process it renders the page. PS. Browser engines are programmed to give the impression of speed by rendering pages *before* they complete downloading. This decision making process involves the different elements on a page (text, scripts, images, etc.) and the observed behaviour may be related to the way that FF/Konqueror treat different elements during a slow download Vis A Vis Opera, or other browsers that don't suffer as much from this problem. -- Regards, Mick
