1. Start the Swingset demo (lets' assume on Solaris).
(Motif L&F is the default)
2. Select the internals frames tab.
3. Check the iconifiable checkbox in the internal frame creator window.
4. Create an internal frame.
5. Iconify it.
6. Select the Java L&F from the options menu. The look and feel changes
to JLF. So far so good.
7. Deiconify the iconized internal frame (from step 5).
The frame shows up in the Motif look and feel.
