Hi Tim,

I doubled checked the files and the short is there.  Since this was a
prototype I didn't feel that I needed to spend the extra money on
having the board house do electrical testing.  Most of my designs
aren't "bleeding edge" so they have pretty wide gaps between
components and traces so I thought that even with under-etching I
wouldn't have a problem.

boards (usually production boards), that come back with unexpected
shorts between traces.  These result from "under etching" at the board
house, which is why they offer electrical testing.
