Hi Richard,

this is a known issue related to limitations in current browsers. For
example with FireFox the SVG elements are opaque, i.e. DOM elements
that are under the SVG div (in terms of z-index) don't get events. I'm
sure if IE suffers the same, I recall someone reporting that IE didn't
have the problem (which puzzled me somehow).

Cheers,
