And answering my own question... Closing SyncBack doesn't write the 
registry capturing the data change. Apparently only closing Windows 
does that. Not good (wonder how much other stuff falls in this 
catagory?). I had already asked about an option to store the program 
data in an .ini instead, and that's... coming. Just trying 
understand all this. And apparently the only way get a "complete" 
registry is stop Windows & copy the files.
