Hi all

    I am experiencing a (minor) refresh problem under WinXP SP1 when I use a
    ProgressBar associated to a TreeEditor. Here they are the steps to
    reproduce the problem
    1) Run the SWT example (source code underneath)
    2) Expand the tree
    3) Enlarge the before last column leaving the progress bars partially
    visible
    4) Use the scrollbar (scroll right)
    5) All the progress bars are partially visible

    The problems disappears if I force a refresh, for example resizing the
    window manually

    I tried under Linux-gtk, but there it works fine.
    Please, could someone help me? Am I doing something wrong?
    Could it be related to

    Thanks
    Salvatore
