Setting Size of Switchboard

I created a switchboard using the wizard, and I would like to permanently set
it's size. When it is set up with sizeable borders, it retains the last size
I make it. When I set up the borders as something else (i.e. thin, dialog,
or none), the width is the way I want it, but the heighth is not (it is way
to tall, shows too much white space at the bottom). How can I set the border
to thin and yet be able to set the size of the switchboard? Thanks for the
help.
