I was experiencing some issues with these ads too, even with NoScript turned off it glitched occasionally. (It pains me to have to leave it on, but I got a rather nasty infection from the ads some time ago and I'm just not comfortable without it anymore. I don't download much these days, though) I wrote a very simple userscript to get past that ad (only that ad, not the others) for people who really can't go without their NoScript/have problems even with JS enabled. I'm making this available with good intentions, but if you'd prefer it wasn't around, Robin, I'll remove it.
