The streamline code was revamped to be more "realistic" so it
will look different than the previous version.  When you say
"strange" does that mean different or inaccurate?  If the latter,
can you provide a screen shot with the old visad.jar and the new one?

Can you provide some code which produces this problem?  What is
the data type of the field?
