Nope - I think candlefish has got it exactly right. Apparently the complicated maths that go on in the background during Select > Modify > Contract/Expand have problems with holding an exact shape (such as a perfect circle) if the modification is more than a few pixels.

Make your selection, then use Select > Transform Selection and drag one of the corner handles. If you hold down Shift+Alt while you drag, the circle will be sized proportionately and centered.
