Hi all,

I've got a rather odd question. Could you please run the attached script, and see if it gives you an error?

The thing is that I have a trial which continuously updates the color red of a rectangle shape.

It always gives me an error, this error to be specific:

---
Unknown system error.
Line 760, File .\DirectDraw7.cpp
DirectX Error DDERR_SURFACEBUSY (0x887601AE): Access to this surface is being refused because the surface is already locked by another thread..
Line 644, File .\DirectDraw7.cpp
DirectX Error E_ACCESSDENIED (0x80070005): Access is denied.
Line 160, File .\DirInput.cpp
---

If I change the shape of the dot into a circle, this problem disappears.

Can anyone replicate this problem, and what might be causing it?

Thanks in advance,

Maikel
