Thanks a lot for this hint. I finally found time to look
into the 
issue. I am using the value 4 at the marked locations now.

...
  if ([_tableView allowsColumnResizing])
	{
	  /* Start resizing if the mouse is down on the bounds of a
column. */
	
	  if (location.x >= NSMaxX (rect) - 4) // <-------
BUST
	    {
	      if (columnIndex != ([_tableView numberOfColumns]))
		{
		  _resizedColumn = columnIndex;
		}
	      else
		{
		  NSLog("ohoh");
		}
	    }
	  else if (location.x <= NSMinX (rect) + 4) //
<------- BUST
	    {
	      if (columnIndex > 0)
		{
		  _resizedColumn = columnIndex - 1;
		}
	    }
	}
...

This makes me a happy camper! I recommend these values for
the public 
tree.

Regards,

   Andreas
