[Trlog] URGENT! Serious bug logging ARRL 160 exchange in 6.91

[Robert Brandon]

I just got off the phone with N3BB.  He was setting up 6.91 for the ARRL 160
contest and noticed that even though he typed in the section it disappeared
when he logged the contact.  He couldn't see the section in the last five
QSOs window.  He looked at the DAT file and the section was not there.  TR
still required the exchange before logging the contact and wouldn't accept
an incorrect section abbreviation.  But once he hit the enter key to log the
contact, it vanished.

I was able to recreate this problem on my machine.  Jim downgraded to
version 6.74 and the problem went away.
