title: Listbox: how to scroll many items, with columns, vertically?
body: <p>Total Commander has Listbox which can scroll, in Thumbs mode, vertically, with N columns. If 100 items, then line 1 has N items, line 2 has N items,.... and scrollbar is vertical. I cannot do it in Delphi7. I added 100 items and set <code>Columns=4</code> but scroll is horizontal.</p>
  
  <p>How to make it vertical?</p>
