menachem and Jay: if you are webmaster of such site or if you can get in touch with the site manager, then you can notify them of cross-browser and W3C compliant alternatives for DHTML newsticker: Cross-browser and web standard compliant Stock Ticker example http://web.archive.org/web/20040202191024/http://devedge.netscape.com/toolbox/examples/2001/stock-ticker/ and Comprehensive W3C web standard compliant alternative to <marquee> http://web.archive.org/web/20040202065251/http://devedge.netscape.com/toolbox/examples/2002/xb/xbMarquee/ I checked the http://www.ynet.co.il page and the news ticker (DHTML marquee) is the cause for the cpu overload. The page is also *_very poorly_* coded: 71 font elements, 117 nested tables, 335 markup errors, lots of javascript functions and overcrowded, loaded animations makes that page extremely demanding on user system resources.
