I'm really a bit confused over what value "mapbox.js" is. It sure doesn't seem to be doing very much of anything useful.
I mean dragging the map, sure, but that's easy enough to do with its help.
And in any case, because it is taking control of the mouse while the mouse in inside the map, you can't use the onclick to show the info about the cell clicked on.
I can't imagine it would take more than a couple of hours, at the outside, to do all the USEFUL things it does, and in vanilla JS code, not jQuery. And at the same time fix the onclick.
But this is New Year's Eve, and I'm close to hanging it up. Only 6:20 PM here, so still time to get ready.
May 2013 be a huge improvement on 2012.
