Hi Kevin,
yeah, adding more stuff to the top line will break it. (and trailing spaces are hard to see.)
It's worth pointing out though that Wolfgang's webinar was done with an earlyish build of NetTalk 4, and is around 4 years old now. We've moved on a tad since then.
Experience over the years has demonstrated that it's better to "embed html inside a nettalk app" then "embedding nettalk in an html app". In the long run it's a lot easier to do the former, and a lot harder to do the latter...
just a thought....
Cheers
Bruce
