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 https://bugs.eclipse.org/bugs/show_bug.cgi?id=95563?

Thanks
Salvatore

Please enter a bug report with the steps and a screen shot of the partially
visible scroll bars. I'm running the code and following the steps but I
don't see the problem. Thanks!
