Fight computers

We hope to have our first seminar-at-a-distance tomorrow morning, with a friend speaking from his home in Australia, fourteen hours later in the day than us.
Unfortunately, we've hit some software glitches, which are getting in the way of everything being smooth sailing.  Here's hoping that I can fix some things at 6:45am in order to be ready for the pre-talk set up at 7:30, so that at 8:00 everything will magically go well!

Yours, reaching for the moon?
