Description of Problem: Browsing through various experiments on http://www.colorado.edu/physics/2000/ site kills eventually both Mozilla and Netscape. "Bose-Einstein Condensation" from "The Atomic Lab" seems to be specially adept at this. Using Java plugin from the latest j2re1.3.1 from "Blackdown" seems to help a bit but not entirely. Yes, I know that the site in question is most likely full of bugs but leaving a locked up and hard to kill window is not very nice.
Fixed in rawhide.
