ListView with ImageViews for cells very bugged?

[John Hendrikx]

Hi Ajit,

Thanks for checking, that is indeed a bit of a beginner mistake there... 
sorry for that.

I added the line, and it is much improved (luckily), but I still see 
issues 2 and 3.

I can narrow down 2 a bit.  When there is only space to show a single 
row (or less than a single line), the scrollbar won't respond to clicks 
in the empty area.  When at least a full row is visible, then it starts 
working normally.

I wonder if it might be possible to warn if that line is missing 
somehow, or provide a different method to override that doesn't require 
calling super.

I didn't see any exceptions, just that the scrollbar is unresponsive 
when clicking in the empty area when less than a full row is visible.
