- Launch SwingSet2
- Minimize all internal frames (except the palette)
- Click on the handle for minimized frame 0
- Notice that the only indication that it is selected is that the button gets focus

Problem 1: Focus on the button is not enough to indicate that the frame is selected. Instead, I recommend that the handle be painted in the "active frame" color.

- Now hit TAB twice.
- Focus goes to the button on another iconified frame.
- Hit CTRL-F5
- Notice that frame 0 is restored, not the other frame.

Problem 2: Button focus should be kept consistent with the active frame. That is, when one TABS or selects the button of another internal frame, it should become the active one.
