z-index problem with VR Keyshot in Chrome

[Grant]

Hello, can anybody help with this problem?

I have embedded a VR Keyshot clip into a web page (it's working fine in all browsers), the problem I'm having is that right next to the div containing the VR clip is a sliding out menu bar. You can view it here http://pattonnz.businesscatalyst.com/unit#anchor-link-1  The problem is that in Chrome the sliding out menu tabs are being covered up by the div containing the VR clip. All of the styles affecting the slide out tabs have a z-index of 1000 and all the styles affecting the VR clip container have a z-index of 1.

Is there anything in the KYSHotVR script itself that I can adjust to make it behave correctly? Or any other solution?

Thanks in advance
Grant
