To do this, use the "event trigger" mechanism (see the FAQ and "UsageEnvironment/include/UsageEnvironment.hh").

I somehow didn't think about that I was calling shutdown and issue PLAY-commands (seek) from my own thread (since it usually works fine). Looking at the example code I however thought it was safe to schedule tasks. After reading your response above I'd like to verify that what I do is correct.<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Calibri","sans-serif";color:black'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-family:"Calibri","sans-serif";color:black'>My question is...
