Windows 8.1 support ?

[Teybeo]

Hi, recently I've been adding support for WebVR in OSGJS but it seems like WebVR isn't working on Windows 8.1 with your 33.0a1 build.

(Here is the hmd initialization in OSGJS)

Windows 7 64bits and Mac 10.9.4 have been tested and works fine with both yours and toji's chromium build.
On the windows 8.1 laptop, WebVR is working in the Chromium build but on the FF build, mozGetVRDevices passes an empty array to the callback, not even a fake device.

navigator.mozGetVRDevices( function(){console.log(arguments) } )

I can confirm Windows 8.1 not working, no matter if wscript or ovrservice is killed or not (in extended mode).
