A third idea is this...

When you enter 'help mode', add a transparent component (ie. iconless jlabel
without text) to BorderLayout.CENTER of your JFrame's glass pane, and give
it a mouse listener. Since the glass pane is above the normal contents of
the window, the jlabel will get all mouse clicks (except in the menu, but
that's life).

Then use contentFrame.getComponentAt(mousePoint) to find which component was
clicked, and remove the jlabel (perhaps it's enough to remove its mouse
listener?)
