BTW, I found a small anomaly with the SN10B v237x1 firmware. Actually, it's with the HL32.EXE program that is used with it in the C:\SN10 directory. Version 237x1 firmware in the cockpit during flights/contests behaved normally in all other respects.

When downloading a flight from the SN10 using the serial port with the HL32.EXE executable, it fails to save a complete IGC file. When I reverted back to an earlier version (ver: 235) of HL32.EXE, downloading of igc files worked perfectly.

Dave Nadler is aware of my instance of this problem. I rarely download igc files from the SN10 (once or twice a year).
