[osg-users] databasepageloader and composite viewer

[Robert Osfield]

Hi David,

I've had a quick check through View.cpp and the destructor doesn't do
anything more than unref the Scene object that should be shared
between each of your views, and as such shouldn't actually do anything
to the DatabasePager directly.  The same goes for
CompositeViewer::removeView, it shouldn't change anything with the
database pager directly.

Do each of the View have their own GraphicsWindow?  I wonder if this
is where the problems stem from.

Robert.
