I'm trying to get comfortable with the syntax search feature and I did a test search that I'd seen in a Logos training video. Now I'm trying to modify it to make the results even more accurate, but I've run into a problem. The window only shows about half of my search query and it won't let me scroll down to see/modify the lower section.

I can't see any part of the query below this in the window, even though there's a fair bit more. Has anyone else experienced this or know how to solve it?
I'm running Logos 4.6 and OS 10.8.1.
Thanks, Ryan
