not seeing any picture in the wall thickness visualization

when i click on the view wall thickness warning I don't see any pictures of where the problem is

This typically means that your browser is not capable of rendering WebGL content, or that you need to enable it somewhere in your browser settings.
As far as I know:
- in Chrome and Firefox it should be enabled by default
- Internet Explorer needs a free/shareware plugin from iewebgl.com
- in Safari, it can be enabled through the "Develop" menu

I don't see anything when using internet explorer (I don't have the plug in). I just fire up chrome and there is no problem.

Thanks for the help
webgl was turned off in my foxfire, turned it on and it's working fine for me now.
thanks again
