about 3D with latest 4.6RC's

[Baldrick]

I tried a many of the example 3D code snippets included with the 4.6RC2 and am having some sort of issue with IMA read errors on a lot of these which all seem to point to the Renderworld() command.
I have found that setting OpenGL in compiler options subsystem will allow many of these examples to run, although most of them still tend to crash with a Win7 message saying the program has stopped responding, but only in fullscreen mode with windowed screens seemingly working ok.
Just wondering what I might be missing here as in what do I need to set to make these examples run properly?
Is anybody else experiencing similar issues?

Please remind, the engine3d.dll is constantly changing with every new beta. So it should be ensured that these (if there any) was also updated in the Windows \ System32 directory...
