Ugly flickering in some views

[Germán Arias]

I have a problem with FisicaLab in SVN (I can't reproduce this problem 
with other application).
In the elements for static of rigid bodies, that are inside a 
scrollview, when I use the mouse
wheel to navigate all is OK. But if I use the scrollbar or the arrows, 
when I move to down, the
view show an ugly flickering. The content of this view is a copy of 
the content of a window
(staticRigidBodies.gorm file). This worked fine previously. So, I 
don't understand where is
the problem here. Thanks.
