I have tried writing explicitly "at first 0.0,first 0.0" , but the result is identical. Indeed, I must write " at 0.0,-2.0" in order to have the ellipse drawn with its center at the origin.

I only see that problem with version 4.6pl5 and older, but not with
4.6pl6 or any 5.0 release I tried. Must be some long fixed bug.

Can you upgrade?
