Please launch the attached snippet, put the focus in the right text field. Then click-and-hold the left mouse button on a unselected tree node. It will show strange gray area.

This seems to be related to the tree item's text (though when using owner-draw, this should not be used): change

  TreeItem iItem = new TreeItem(tree, 0);
  iItem.setData("TreeItem (0) -" + i);

to

  TreeItem iItem = new TreeItem(tree, 0);
  iItem.setText("hello world");
  iItem.setData("TreeItem (0) -" + i);

and the gray area will be much wider.

The work-around is to not use the SWT.FULL_SELECTION flag. :(

I can't reproduce this problem any more.
