Sweet Home 3D viewer - space bar doesn't toggle viewpoint

[AndyWas]

I am using the Sweet Home 3D viewer to share plans with some builders. However the space bar doesn't toggle the viewpoint between virtual visitor and aerial view as described in README.TXT. This is in Firefox 12 on Fedora 16 (kernel 3.3.7-1.fc16.x86_64).

Any ideas or suggestions?

Thanks,
Andrew

The space bar key would work only if the viewer has the focus. Please, try to click in the viewer first.

Toggle works OK in Windows in Firefox and Internet Explorer (though 3D rendering doesn't really work in IE8...mostly just red boxes). Maybe an issue with the JDK on Linux?
