Will try changing the pixel format tomorrow and let you know how I get on ...
Thanks for the help!

Hi,
I create my class derived from wxGLCanvas like so:
// Canvas
int attribList[] = {WX_GL_RGBA, WX_GL_DOUBLEBUFFER,
WX_GL_DEPTH_SIZE, 32,
WX_GL_MIN_RED, 8,
WX_GL_MIN_GREEN, 8,
WX_GL_MIN_BLUE, 8,
WX_GL_MIN_ALPHA, 8,
WX_GL_AUX_BUFFERS, 1,
0};
m_CViewGLCanvas = new CViewGLCanvas(this,
-1,
wxPoint(0, 0),
wxSize(512, 512),
wxNO_BORDER,
wxT("CViewGLCanvas"),
attribList);
