[OpenLayers-Dev] Exception in OpenLayers.Layer.Grid.removeBackBuffer

[Tim-Hinnerk Heuer]

Hi Tobias,

Sorry for taking a while to answer, but I was flat out busy. I'm the only
JavaScript developer at my company now and getting over-loaded with work...

If I am to present this, I will make the material available online if my
employer allows, which I'm sure they will. So, if you follow me on Twitter,
you will know when and where things are.

I will also post it on the mailing list.

It's (funnily enough) just not working properly in Chrome yet and of course
IE. I don't know if I will even bother with IE, because of different video
codecs and licenses unless they decide to make their standards a bit more
open. As soon as there's a live version of our stuff I will let you know.
It was a proof of concept first but works quite well at least in Firefox.

Cheers,
Tim
