3\ Regarding driver mess up mentioned in comment 15, I once checked hardware
capabilities (3D rendering etc.) and followed some notes found on the Internet
to upgrade video drivers, but then rolled back the changes as far as I could.
More precisely it was about the OpenGL version supported on the system.
