On further thought, this might be a 'useful' quirk or design.

For a very large powerpoint (say 50 slides) it takes a good few seconds for openlp.org to load all the slides. If I want the timed slides to say co-incide with a music track, this delay would be a tad annoying, so the ability to start it myself once it's loaded is handy.

Once you've 'gone live' on a timed powerpoint, click the first slide in
the live panel to start it going. This seemed to work reliably for me, rather than attempting to go live twice.
