Yes, but Panel2 not follow the size of form/scrollbox.

Just "remove anchored bottom of Panel2" then start the example and click 
on Panel3 and will see what I want. The vertical scrollbox showed up and 
the user can scroll the panels. It's good but the Panel2 not resized 
with the form/scrollbox without the bottom anchor. So if bottom anchor 
of Panel2 exists the resizing of Panel2 work as expected, if removed the 
anchor resizing (by the user) of Panel3 work as expected. But I need the 
two features coexist.
