Hmm.. I'm *still* having issues with this.. it seems that if you start the tournament "Controls->Start Tournament" then everything works ok..
However, if you use the countdown, i.e. "Controls->Start Countdown" and have the tournament start when the countdown ends, the first round duration *is* always wrong!
My "Start Tournament Countdown" dialog is set as follows:
Countdown a specific length of time, 00:30:00
When countdown ends, start the tournament
Start Countdown Now
Please can someone else try this and confirm...
