You can easily reproduce the problem by using my sample program. Let's name
it SimpleTableDemo.java. After generating the byte code, you are able to bring
it up. Please try to shrink the SimpleTableDemo widnow size a little bit and
you will see the bug. There is NO scroller on the horizontal scrollbar.
