Thanks for the responses folks. I’m still tinkering about with some of the CSS but I’m pleased the way it’s turning out.
I’m really puzzled about the problems you’ve had Aesop. My main browser is indeed Firefox, but I’m a stickler for compatiblity and none of the problems you’ve mentioned appear on my IE (V6). The only ‘problem’ I’ve seen is if I scale the fonts up by three clicks, then the header of the first post appears after the sidebar (FF works fine though).
I’ll certainly keep experimenting though, trying a different version of IE at work and get a few other IE users I know of to have a look, but I really appreciate the feedback, thanks for that.
