Answer 1

I think the problem might be that the frame hasn't had time to repaint itself before the Robot starts.
From the Robot API I see the following method:
public void waitForIdle() - Waits until all events currently on the event queue have been processed
There is also a delay() method that might do something.
This is just a guess, I haven't tested it.
