Thanks!

Oh, I guess I should have searched the mailing list first (I
usually do). I'll have to take look.

The face is defined by sml-mode, which is required at the beginning
of esml-mlb-mode.el. I fixed this by duplicating a face definition
from sml-mode.

I can't reproduce the problem. Seems to work (as intended) on my
machine (on both GNU Emacs and XEmacs). Could this be caused by
the missing face?

I uploaded the fixed version as esml-mlb-mode.el.v2. Feel free
to rename the new one and delete the original if you can. The
Wiki interface doesn't let me do those operations (for a good
reason).
