After an epic journey, I found the answer!

the line:

-moz-user-select: none;

Must be added to the CSS of #sheet

Hi,

I am using the Google SketchUp Web Exporter to create an HTML page of my model. It works great, except one thing. In Firefox, after the first click/drag (which spins the model fine), any subsequent attempt to click/drag the model results in the mouse being 'captured' by the model and not dragging when the mouse button is down, only up -- when it's down I get the ghostbusters sign. This does not happen in either Chrome or IE, so I think it has to do with the way FF is handling the Javascript. Would appreciate any help, as my JS is very weak.

Thank you in advance for any help!

Here is the code that the exporter generates:
