CHIRP

I'm using the latest Mac build (chirp-daily-20130218) from development and uploading back to my FT-7900 (that has worked fine in the past) but I keep getting "Radio did not ack block at 31624" at the end of the upload. Everything seems to have uploaded fine, just thought you should know in case there was a change recently that may have broken something, or caused an erroneous error display.
I had chirp-daily-20121116 in my downloads and that one doesn't produce the error. I can do some further testing if you need me to figure out where it starts.
