I've asked friends to check the problem sites out & they work fine for them. This means the problem is somewhere on my system. I'm using WinMe + IE6 with all the latest updates. Maybe someone can suggest something.

Here's 2 examples.
Shoreham Airport index page. http://www.shorehamairport.co.uk/default.asp
Airliners.net http://www.airliners.net
Thanks for any suggestions.
