Hello,

I just got back to the machine that had this problem and that led me to
submit bug #863742...

... so thanks for your pointer to #802061 within 48 hours.  It seems to
have worked just fine.  I wish I had been able to dig it up myself but
the process is rather convoluted (and while I'm an 'old' Unix user
(fwiw, I remember System III), I am not experimenting with Ubuntu other
than as aa definitive low-cost alternative to Windows XP...

I also thought I'd share this with the last person to post on this
subject because you seem to have made the fix permanent...

... so thanks for that, too, but I must admit that I'm intrigued by the
fact that I still get announcements.  I may try to "unsubscribe" from
the reports but am more curious by the long tail of issues that people
experience.

In any event, keep up the good work.  Thanks again.

Edward


First and foremost,
