The solution from the first link works, however what it does is scroll the selection. I have a multiselect listbox and what I want to achieve is to be able to select some items when holding CTRL and still be able to scroll down to select more. At the moment when I select some items and then scroll down the selection reduces to just one item which is then being scrolled. Also when I scroll it starts from the top and before I reach the last item on the visible part of listbox (so effectively start to scroll) I have to rotate the wheel like 3 or 4 times.
In other words is it possible to scroll not through the listbox's items, but the strip on the side of the box?
Any suggestions?
