There is an article at [link] about off-screen positioning versus clip (something which I've not tried). I'm using off-screen absolute positioning, though slightly different to the example in that article, but I can't replicate the page jump problem that this writer mentions. I have tried it in Firefox 3 (and latterly 8), Chrome, and Internet Explorer 8. So does this happen? Does it affect only browsers that I don't have, or what?
