screenshot error
 

Hi,
When I try to save a screenshot in ParaFoam, I get the following message

OpenGL Warning: glXChooseFBConfig not implemented by Chromium
OpenGL Warning: glXChooseFBConfig not implemented by Chromium
OpenGL Warning: Unsupported GLX Call: glXCreateGLXPixmap()
Segmentation fault

Printscreen doesn't seem to work either.
Is there a solution to this?

Thanks.
