I found it myself now, finally after 3 hours.

ScrolledPanel.OnChildFocus() scrolls to the selected child. In my case 
this is not good, because the child itself has a lot of childs 
(textfields). So clicking one of these textfields at the bottom results 
in the fact that the parent panel (the child of the scrolledpanel) is 
scrolled to, putting the textfield out of sight again.

To remedy this, I overwrote ScrolledPanel.OnChildFocus() with this:

def OnChildFocus(self, evt):
     return

This works. I hope this doesn't violate or break some other things that 
are vital (?).

Best regards,
antoine
