The problem can be reproduced by simply changing the osgpick example to
use a CompositeViewer with a single view initialized using
setUpViewAcrossAllScreens(). I have attached a modified osgpick.cpp so
you can test it out quickly (please don't check this file in though :-)
) The eventState is then incorrect and picking does not work. The only
changes are in CompositeViewer.cpp (eventTraversal() method), and fix
the problem for me.
