No, I actually have to edit the #lang line. I just tried this on a Windows machine running DrRacket, version 5.0.1.5--2010-09-09 with the file I sent and get the same behavior. Switching languages -- say from "Determine language from source" to "Beginner student language" doesn't help -- when I switch to BSL, the "step" and "check syntax" buttons appear, but then disappear when I switch back. If I just click on the #lang line and type a space, though, the buttons appear.
