There's a plugin in your doc called "CustomTracker" that is
incorrectly hijacking the wrong function... SinglePageModePlugin
hijacks Story.prototype.displayTiddler() so it's added features are
applied to every 'Story'-classed object present in the TW runtime.
However, CustomTracker plugin is replacing story.displayTiddler() in
the specific instance of the global 'story' runtime object creating
during startup. Because the changed function is being assigned
directly to an object, rather than an object *prototype*, the
overridden function is being invoked instead of the one assigned by
SinglePageModePlugin.
If you disable or delete the CustomTracker plugin, things may just
start working....
