I see here the Hans touch again: it's better and I don't really understand  
how it works :-)
But there's something strange: the first circle is greater than the others  
(but the numbers have all the same size). Tracing a bit I see that the  
first circle has a width=16.5333pt, the others 13.19997pt. What's the  
reason for this?

Thanks much!
