<html> <head> <style></style></head> <body class='hmmessage'><div dir='ltr'>Hi dear Gate users I am working with Vgate 3.0 , Since a moment I had a graphical problem, I designed my scanner but I can not see it when I run Gate, I have a black window in the viewer and I get this messages in the terminal . It seems to be a vido configuration problem with virtualbox. I read in virtualbox forums and I am not the only person that having this problem. But not solution found till now. Does anyone have an idea how I can fix that :( WARNING: G4VisCommandSceneHandlerCreate::SetNewValue: using fallback graphics system.
