Twice out of 3 times over the last 4 weeks when I attempt to inject an ad hoc OSB reference during the Pastor's message, the background music (I think from the pre-service loop, but could be post-service?) has played. Not good. The very first time I tried it (9/21/14) it worked fine. But on 10/5 and 10/12, music interrupted the sermon.
There's not even a control on the screen for volume when the OSB is displayed. My sound person had to jump on the Mute button, but the damage was done.
I'm pretty sure there was at least one software update between week 1 and week 3, so maybe that's the culprit.
Help?!
