Problem with DrawOval

I can't get drawoval to work (under windows). I noticed that some other people raised this in the 1.10 update forum thread but can't seem to find any notes as to whether this is a bug or not. The example in the help doesn't work for me either - no ovals are drawn at all.

Does anyone know whether this is a bug, or if not what I need to do to get it to work? DrawLine and DrawText seem to work fine. However DrawPoly doesn't seem to work either. My machine has directx version 9c running.

Cheers,
Tim

I get the problem with DX driver but not OGL driver on my laptop with S3. Problem doesn't occur on my PC with 9800Pro
so, I'm guessing, it's a DX driver issue.
