Hi Robert,
I will send you a complete dump file in the evening (local time Germany). There 
is currently no way out here. ;-)

setup

Hi Thomas,

Thanks for the details. 

The stack trace is a bit too incomplete to be able to spot where exactly the 
problem might lie.    In particular the [Externer Code] should give us an idea 
how StandardManipulator::centerMousePointer(..) is eventually calling 
GraphicsContext::getTraits().


Robert.

 If you have a
multi-monitor setup (e.g. 2 Monitors attached) running the latest stable
release 3.4.0 of OpenSceneGraph, the application crashed at startup when no
--screen parameter is set. (OSG tries to use all monitors by default, worked
with 3.2.3) This doesn't happen if you explicitely call osgviewer --screen 0 to
start rendering only at one screen.                                       


What hardware and OS combination are you seeing this issue with?

Could you build the OSG with debug and see where about the crash occurs?  A 
stack trace would be very useful.

Unfortunately I don't have two monitors available to test right away, but 
should have one by next week so will test then.

Robert.
