I'm of the opinion that some websites will crash some browsers some times; as bland as that sounds.
I went to braums.com (as in the ice cream place) and that wasted not only my netscape process, but hung my session such that I had to have someone else kill the process from his box. I'm on a Sun Solaris UltraSparc5 w/ netwcape.
So, the way I see it, its kinda an issue that just exists; a website will occasionally give your http browser some code (be it html, xml, activeX, etc..) that breakes it (at least in the current session you have with the webserver hosting the site your viewing).
