Windows doesn't cut the letter off, but it does jam
the button frame up against the base frame in a way that
doesn't happen to the frames on the left. It looks ugly,
but, ... well, what else is new? Something is not right,
clearly.

Oh, Lord. Would this be a *paid* internship? I've got a couple
of young men at home who are looking for a job this summer. :-)
