Line pointed to center of circle

[Kaminar <Kaminar seznam cz>]

Hi,

I have one problem with anchoring the line to the center of circle (ellipse). If I
drawing a line to center of a circle, the line is anchored to binding point at
border of circle. Only one solution which I found is that It must first
draw line and then place circle over line at right position. This solution
would be sufficient, but there is another problem with it. After move this
objects, the line anchoring change from center to border of circle. Is there any
way how to avoid this behaviour?
