Hi Peter,

still blank white unfortunately. Do you have a colored background? If so, then that would indicate a problem with the render context or buffer swapping. Something fundamental anyway.

It's not a gpf or a lockup. It just does't put anything into the client area except for white. For some reason, Opengl has not engaged. Normally you get at least a black or transparent screen in the early stages.

I have a standard piece of code called OpenglScenFrame.inc, which I use on a number of demos. It has all the essential steps.

Do you use the standard ChoosePixelFormat? If there is a problem here, it could cause incompatibilities.

my example with openGL and "OpenglScenFrame.inc" are all working here well. may be it's worthful to expand this library too.

Hi Frank, Got your rotating pyramid and also drag-and-drop so far. I'll get to the crate examples ASAP.

A combination of dragandDrop and Opengl Sceenes would offer great possibilities.
