Thanks Gino, changes merges and submitted to SVN. Thanks also to JS and Jan for engaging in discussions. I have little expertise with OpenVRML or Windows so can't make many judgements about these things.
W.r.t use of which version of OpenVRML going forward, this is an awkward one, the OpenVRML developer making it more awkward... this is an issue to flesh out more on osg-users. If there is consensus on moving to the later versions of OpenVRML then I'm prepared to go with this. Robert.
