Jim,
       I will check in the fixed for the bug and you should be able to get the 
nightly earlier this afternoon. 
       This bug is related to the setting time driver in the animation widget.
       I tried your bundle and the timing seems right to me even though you 
will still seeing 
reading data for many times, those message might not be corrected. I set the 
break point for the data 
reload, and make sure only happen one time at the beginning.
