I'd be happy to not use frames, but I don't have the choice at this
time because the application is already written using frames and time
won't permit a total rewrite---at least that was our thinking when we
decided to leave most of the application as-is. From my experience so
far, I guess we should have just abandoned frames because it's harder
to work with them using Wicket. That's no fault of Wicket---it's
designed for panels and not frames.
