I run a testprogram: http://pastebin.com/G8e6PqDn

The output on the problematic laptop is:

can run OpenGL 4: false
can run OpenGL 3: true
GL version is 3.2 (Core profile, arb, compat[], FBO, hardware) - 3.2.9262 Core Profile Context
GLSL version number is 1.50.0
GLSL version check for 3.30 returns: false

So it's exactly one minor version away from supporting OpenGL 3.3. I guess the test for GL3 returns true for any 3.x version, which is not enough to determine if 3.3 is available.

I think I will first check if OpenGL 4 is available and if it is not available create a fake window to create a GLContext that I can ask for the exact supported version.

Thanks for the help
