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.

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.
