Hi zhuwan,


did you started osgviewer.exe without --screen parameter?
Everything is working if I add the --screen 0 or --screen 1 parameter, but it 
crashes when no parameter is given. I updated to the latest Driver and the bug 
is still there (for me).

hi Robert,
  I always use dual monitors to run osg applications,and always test osg newest 
versions,the newest osg version tested is just 3.4.0,have no problem in dual 
monitors configer,i thing thomas maybe used a bugged nv opengl driver,sometime 
nv also release bugged
 opengl drivers,when update to the next version's nv driver,the crash maybe 
disappear automaticaly.
  Robert,are you rember one of my messages in the osg user lists point out the 
NV and AMD's Opengl drivers buggers???

Hi Thomas,


My second monitor has just arrived so I have been able to test OSG-svn/trunk 
(essentially OSG-3.4.0 with only tiny changes) under Linux and Windows with 
dual monitors.  So far everything is working as expected, no crashes.


My set up is iCore7 + Geforce GTX 760 + Two monitors + Windows7 x64.


This would seem to be a pretty similar setup to your own.  At my end there 
isn't nothing more I can do as I'm not able to reproduce the crash and the 
stack trace I've seen so far doesn't provide any indications why you system 
crashed.


Perhaps others can test out under Windows as well to see if there is any 
pattern of failure.  


Robert.
