Hi

I'm guessing that BB is using a frameset to achieve this?  If so, the BBC site is one of a number that have their own JavaScript code to break out of the frameset.

I ran into similar problems when developing the INHALE/INFORMS materials and had to resort to using two separate browser windows - e.g. http://inhale.hud.ac.uk/perl/jump.pl?1-4

If BB is using a frameset, then there's not really any way around the situation apart from utilising a proxy to intercept the page requests are parsing them to remove the "frame busting" code.
