I just opened the RD Picker on my (912) installation
pressed rebuild, completed
demoed two drums, no issue
OK'd one of them, it loaded and played
<repeated> no issues

One thing I do notice is that the FlashMessageLog.txt now has binary in it, and that ain't pretty! The binary characters just arrived in today use with the RD Picker.
