I recently completed a site for a friend http://www.inescole.co.uk
It appears fine in IE8, Chrome, Firefox and I think IE7. But the owner sent me an email with a screen print showing the problem. The only thing that is different is that the bar at the top says "Internet Explorer provided by BSkyB". Could this be the problem? I have attached the screen shot.
It seems to me that that browser is ignoring all / some of the CSS file rules.
Any ideas? Has anybody else come across this problem.
