Resize the right hand Layers pane in Dia 0.97.1 for Windows 7?

["Andrew J. Leer" <leeand00 hotmail com>]

When I move my mouse over the side of the pane (see image in attached
link), I don't get a resizing arrow or anything, and the space in the
pane is really cramped, is there anyway of resizing the pane?
