We thought this was a problem in the way we had set up the project but I
wonder if it does affect production.  I'm just hesitant to go diving
into the code too heavily.  However, we saw this error message this

QObject::startTimer(): QTimer can only be used with threads started with
QThread.  Any idea what is going on here? Thanks - John
