The memory lost right at the end of archiving is a known bug at HP and Mr.
Wickes told me it is in all the ROM versions (A to D).  However, it only
happens if you have the clock display on while archiving.  The fix is
obvious: turn the clock off when archiving.  The program I use to archive
(which also saves the flags in a variable) now turns the clock off.  I
haven't had the problem since.  This also explains why some people have
never seen the bug.  Also, the bug is quite intermittent.  It only happened
to me about four times out of many tens of archives.
