Thanks George,

I'd assummed that it was some sort of javascript, but didn't understand what.

I can, of course, turn off javascript, but that's no good if you're trying to direct other people somewhere. A link that says 'You must turn off JavaScript before clicking' isn't likely to get much use...

I don't really understand why the web designer has used such a script. I can't see how it offers him or Topic any advantage. It just annoys people like me and stops me giving them free advertising.
