hi!

I seem to be having a strange problem trying to use a textwidget
within a viewport within a vpane.  Basically, the example below
shows the following on our machine:  as expected it starts up
with a label pane, a viewport pane (containing horizontal scroll
bar and a textwidget child with a vertical scroll bar), and another
label pane.  Now when I pull the grip separating the viewport from
the lower label downwards, i.e. expanding the viewport, the
vertical scroll bar for the text widget doesn't grow;  also the
text widget seems confused about its size as is obvious from
its scrolling. Any ideas?

thanks in advance.
