Might have to go with an iFrame then. And for the record - I wasn't planning to use it as nested scroller - more like a 'popup' with an overlay. Handy for extended alert messages etc. Iframe seems to be the way - even though I really hate using frames of any kind in HTML.
Yeah, really quite familiar with the close button functionality :) Just wanted to know if there was a way to make it a 'back' button. Any idea if the support will ever come? Would be a really-nice-to-have feature.
It's a bit rough around the edges, and especially the performance leaves something to be desired (it's built of animated canvas elements), but IMHO it shows one could build e.g. some nice little games on top of this platform :)
