Thanks Robert, i know that you cant know the problem without seeing the code :) i just want to know that when isVertexBufferObjectSupported() function returns true or false? to use this support should i enable something?
anyway now i will try to make a simpler example, then maybe i could show you the codes.. thanks again...
