   Problem with glSecondaryColor3fEXT
  Hi,when I call:glSecondaryColor3fEXT(v.x, v.y, v.z);where, for example, v = {x=0.68255538 y=0.034517914 z=0.50000000 }I get the following error:"Unhandled exception at 0x00000000 in demo.exe: 0xC0000005: Access violation reading location 0x00000000."Any idea?I'm using the glew library and the code compiles without errors.Thanks.
