On 4.0.6 you don't need to do this, the context is already made current when OnLoad is called. The places where you need to call MakeCurrent is if you use OnResize (which can happen at any point and there's no guarantee that the context is current), or if you switch threads and do something with the context that makes it not current. Any surface creation errors are going to occur before OnLoad is called, during the CreateFrameBuffer call. If CreateFrameBuffer throws no exceptions and OnLoad is called successfully, that means you have a context and a surface and the context is current. andreia gaita ------------------- blog.worldofcoding.com (http://blog.worldofcoding.com) github.com/andreiagaita (http://github.com/andreiagaita) > Sly > On Apr 17, 2012 8:17 PM, "Eduardo Jimenez" <[email protected] > (mailto:[email protected])> wrote: > > Do you mean that you have to stop manually creating the frame buffer on > > loading?
