Hi Mark,
I can't seem to reproduce your issue, but it's a bit difficult without
seeing how exactly you wrapped up the "main" part of the code. Just
guessing: maybe the two cases aren't *exactly* the same.
Is it possible that you have ``lman`` (the LassoManager instance) defined
in the same block of code as ``show`` in one case but not the other? If,
for example, ``lman`` is defined in a method of your class, but not saved
anywhere then it'll get discarded after the method finishes. So ``show``
would need to be called inside that method, or saved as a class attribute.
Like I said, that's just a wild guess. You should paste the class def if
you're still having problems.

P.S. If you're running matplotlib from Github master, you might be
interested in an alternative lasso tool (LassoSelector) that may be
simpler to use.:
