Subject: Changing point size doesn't work well on windows

Open the iceland_sample_class.thuban session and double click on the point
layer in the legend window to open the classificaition dialog.  Double click
on one the point classes and change the size to at least 8.  smaller values
work fine on the system I tested this on and the minumum size to reproduce the
problem may be system dependent.  The result is that the symbol column is
resized and the dialog seems to update itself continuously.  The dialog cannot
be closed properly anymore.  Closing only works on the second try and then
produces a traceback:
