I noticed something, I use Fonts4OS5 to change the fonts for Blazer on my Treo and on the accidental button press, I noticed that Quick Tour is also effected, even though Blazer is the only app registered for that font.

Is it possible that QuickTour is an HMTL-ed app, compiled into a PRC? And if so, couldn't other PalmOS apps be made that would take advantage of (not much to do so) of the PalmOS web browser?

Just a thought.
