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:

and

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.
