Issue Detail: 
On any Etour (www.etour.com) page the Next Site
button is not functional.  This happen on both my
home and work computer.  On other web sites the if
there is a continue or go function it will not work.
----------------------------------------------------

I get "Error: uncaught exception: Permission denied to access property"

I presume it's because of:

 if (navigator.appName == "Netscape" && parseInt(navigator.appVersion) == 4)
   iHistoryEnd = window.parent.frames["etourmain"].history.length;
 else
   iHistoryEnd = window.parent.history.length;

Is it correct that we disallow window.parent.history.length?  If so (why?), 
please reassign to evangelism.
