Oops, thats a pretty ugly screen layout dwanthy! I've pushed up a new version now. I had been through a lot of variations of layout as this was developed and I thought of new customisations, and I'd left some rather crude sizing code in there. The new version should hopefully address your issues.
Let me know how you get on - now I've figured out what to do I'll make sure I don't make the same mistake in my other plugins again.
