// - ParamBlock accessor doesn't work. For some reason, the accessor isn't

// guaranteed to be fully loaded (with their tabs filled) nor are the
// notetracks necessarily attached yet
// - Notetracks can also possibly be attached BEFORE load, which doesn't
// do us a damned bit of good, so we need to make sure we're fully
// loaded before we run this function. Unfortunately, the only time
// we're guaranteed THAT is by a FILE_POST_OPEN notify. (post-load
