Hello. The picture attached and the topic name is pretty self explainatory.
PS: legend for the image - green circle=good; red circle=wrong
Edit: Actually if you want to zoom the image so you can really see what I mean. The picture is located here http://www.pixel-expression.com/sel.png
I wonder if there is a stray anchor point somewhere causing an open-fill. This is typical when a path is not "closed". It's hard to tell without the artwork itself, to see how it was built.
Well, actually, it's always like this. Even if I put a single circle on a magenta background. Wierd
