[osg-users] osgViewer::Viewer fullscreen dual monitor issue

[akaisora at tuta.io]

Hello Rebert,
Thank you very much for your explanation, as I am knew to OSG, this really 
helps a lot :)
My monitors' order is exactly as you mentioned.
Since I am just getting started, I don't really need multi-monitor rendering, 
so after toying with the viewer class, I found out about 
 "Viewer::setUpViewOnSingleScreen" and I set it up to my primary display.
Oh, I tried to look into Windows API to figure out how to fix it (within OSG) 
but realized it's more advanced than I thought. 
...
Thanks again!

Cheers,
Soulaymen
