Every time I try to shrink it back down, it automatically resizes itself to 780 units tall.  Try it and see if you get the same behavior.  I'm running on Windows, by the way.

Ouch! No I didn't try it, but I used to have it at at 4 a while ago 
and assumed it would still work.

You are running the CVS version of Boa?

This uncovered a hack that granulises the frame size when it is resized.

in Views.Designer.OnControlResize change the following:

# Granularise frame sizing so that controls inside main frame
# fits exactly
sze = dsgn.GetSize()
granSze = granularise(sze.x), granularise(sze.y)+3
dsgn.SetSize(granSze)

to

# Granularise frame sizing so that controls inside main frame
# fits exactly
sze = dsgn.GetClientSize()
granSze = granularise(sze.x), granularise(sze.y)
if sze.asTuple() != granSze:
    dsgn.SetClientSize(granSze)

Thanks for picking this up.
