Initial Comment:
Using the "run current document's main method" causes
the following exception to be thrown:

I haven't looked too deeply into the code, but you guys
should be careful about how the stylesList is
populated; it seems to have a null floating around in
it.  I'd imagine it has something to do with legacy
insertion of text into the interactions pane in order
to do the "run" action, but I'm not sure.  The
exception also has an annoying tendency to recur,
making drjava unusable.

Oh yeah, this is the latest CVS, compiled/run with
java-b56 on WinXP.
