Hi Robert, Thank you for your reply!
Probably there is a misunderstanding: osgviewer is not killed all the time. It is started once until it crashes by itself. The "xterm-script" is started in a separate terminal and only opens/closes a single plain xterm. osgviewer runs fine for quite some time while the script opens and closes an xterm on top of the osgviewer fullscreen view. But after a while osgviewer crashes. The script opens and closes an xterm to simulate opening and closing a Settings Window in my application. Once in a while my application crashes after a user opened/closed that window. I found that the same thing happens with osgviewer and xterm. I'm ran osgviewer in SingeThreaded mode. I'd appreciate any further hints, Thanks, Thilo > Hi Thilo, > > This is may well be a driver issue.
