Netscape crashes (closes) when loading web page with java

Hi, have a problem with Netscape (running under Windows XP) closing when loading web page with a popup window using java. Good example is when I try to watch an eBay live auction www.ebayliveauctions.com. MS ie handles the live auctions without any problems. The problem happens with both Netscape 7.0 and 4.79. I have both Netscape programs running on another system under Windows 98 SE that are configured the same, and they run ok on that system.

Has anyone seen this problem and is there a solution?
Thanks.

System config = Dell Inspiron 8200, Windows XP w/ SP1 and many updates.
