What's strange in that? If is not OpenGL compatible you can't hope it
would work!

Hi Paulo,

Just out of curiosity - what is the name of the card that does not support OpenGL and works with Windows Vista? Maybe it is just a matter of installing proper drivers.

Regards,
Orson

In a early version, ex. bzr50106, only Pcbnew closes.

My desktop PC have on board video. I believe that this type don´t have OpenGL support.

On my hp note, with Geforce GT 230M, the OpenGl is supported, and OpenGl mode is functioning.

Would be usefull if the OpenGl mode option were disabled when OpenGL isn´t supported.

You are right. The problem is - you cannot check the supported OpenGL version without creating an OpenGL context and that means you first need to switch to OpenGL canvas.

Maybe some specific wgl/xgl call? or simplying querying for an
extension address of some peculiar function (IIRC you can query them
even before creating the context)
