Could you please switch to using a CompositeViewer with multiple
Views, rather than multiple Viewers, as you usage model is intended to
be supported by CompositeViewer, you are much more likely to find
success/stability when using the OSG in the way it's intended.
Also try moving up to OSG 2.6, 2.7.x or SVN/trunk as there are plenty
of improvements across the board, including to paging and multiple
window work, I can't say for certain this will fix you problem, but
there it's definitely worth a try.
