Look closely - the scene moves, just *very very* little.

It's a bug in osgViewer/CompositeViewer.cpp which I submitted a fix for 
about a week ago. When a single view is on multiple displays (so the 
slave camera mechanism in osgViewer::View is used) the viewport extents 
are not set correctly in the eventTraversal, so when the mouse events 
are translated they have wrong values and the mouse movement has very 
little effect.

I haven't gotten any news about it being integrated into SVN yet, and 
your report seems to confirm it hasn't... Any reason for that Robert? Is 
there anything I need to do to get it integrated?
