Are you updating the mdDate of the section record before writing the
edition data?  If not, the Edition Manager package will see that the
newly written edition doesn't supercede the previously written one
(both dates are the same), and not send off update events.  Why it
bothers to update the file in this case is beyond me--in one case,
it seems to believe you're making significant changes; in the other,
it refuses.  At any rate, try sticking a

  GetDateTime(modifiedNow);
  theEdition.SectionH^^.mdDate := modifiedNow;

before you OpenNewEdition(), and see if this changes anything.  If so,
fix the bugs in your edition time-stamping.  (Or implement edition
time-stamping, if you've overlooked it.)

Of course, none of this explains why it sometimes takes the Edition
Manager 30 or 40 seconds to send out SectionReads when there are only
two applications, both idle, open on an fx.  Some parts of System 7
are like having a Mac Plus again...
