Is there anything I can do to help work on this bug?  If you just
haven't had time, that's fine; on the other hand if you no longer have
access to this machine or have lost interest for some other reason,
that's fine, too, but please let us know either way so we can plan
accordingly.

Thanks for your help, and sorry for taking the bait when reading some
venting last month.  I hope we can get this fixed soon.

Sincerely,
Jonathan
