Cube OpenGL ES 2.0 example on Windows XP with DirectX 9.0c

Hello, When I run the OpenGL ES 2.0 example on my Windows XP box with DirectX 9,0c, I get a blank window with the following warnings/errors. Can anyone shed light, what I am missing? *QGLShader::link: “(35,17): warning X3206: implicit truncation of vector type “ – texture upload failed, error code 0×502, enum: 3553 (de1)* Thanks AB
