Rendering problem when scrolling license agreement in Picasa installer

[Dan Kegel]

http://bugs.winehq.org/show_bug.cgi?id=3348
describes a scrolling problem that is probably pretty
easy to fix.

The nullsoft(?) installer used by picasa 2
seems to have a problem with text scrolling
in the latest snapshot of wine.  Scrolling
using the keyboard works, but scrolling by
clicking on the arrows of the scrollbar
screws up the new text.

I have a sneaking suspicion this affects other
apps.  Is this a known problem already?

Thanks,
Dan

Bug in riched20.dll: the window is repainted before the internal state
of the control is updated.

Change log:
dlls/riched20	: editor.c
When scrolling, first update the new position of the control before
calling UpdateWindow().
