RE: Exception raised when drawing many circles

This exception occurs in my full-size application and I have not been able
yet to reduce the code to a few lines. As indicated, I have generated a PIX
file where the problem occurs. I can send it to you.

If I look inside this PIX file, I can see that at one moment, a call to
DrawIndexedPrimitive made by the Line class returns a D3DERR_INVALIDCALL.
This seems to be caused by a vertex buffer that has not been unlocked by
Line. Here is the point where the problem occurs in the PIX file :

--- We are here inside the last successful Line.DrawTransform ---

--- Here, DrawIndexedPrimitive() has returned D3DERR_INVALIDCALL and will
always return D3DERR_INVALIDCALL after... ---

I hope this will help you.
