Physics demos

[mjabon]

Hello. Every time I run one of the physics demos included in Vizard 3.0 I get the following error:

before Font::Glyph::subload(): detected OpenGL error 'invalid enumerant

Can you explain how to fix this?

Thank you!

This is caused by the text renderer on certain cards. If the text shows up fine then you can ignore the warning. What graphics card are you using?
