A problem that happens in palette and IE7.
Wicket version is 1.3.4 .
The situation is:
when pressing the UP button, the selected element goes up in each click.
The problem occurs when this element is in the second row.
When pressing UP, it won't go to the first (upper) row. Only when we move
the mouse to the area of the selected elements it goes up.
In FF it doesn't happen.
in IE6 it doesn't happen as well.
