how to change UML class box in MS Windows?

["Roby, Clyde G" <roby ida org>]

Hello,

        I would like to know how to change the UML class box in the MS
Windows version of DIA; I have v0.96.1.

        When adding attributes, the text of the bottom attribute looks
like it is directly on the bottom line of the box.  I would like it to
be slightly above that line -- vertical whitespace similar in size to
that between the line above the attribute list and the first attribute
name.

        Thank you.
