I find that at .056 dia the pads are (IMHO) a bit small, so I get the oval effect by using wider tracks. Even with .080 tracks and track spacing set to .050, there's no problems. Another useful feature (once you've finished) is the plane tool, which fills any large expanses with a non connected plane, which won't get etched, apart from the gap between plane and tracks. Meaning less copper to etch. I don't know if anyone else has this problem. I prefer to work looking at the underside of the board, only. In this respect the IC DIL are reversed, being shown as looking down on the component rather than up at the track area.
