Just finished the J120 Nationals and had a new mystery appear on the third day. For no reason that I have yet to discover, the W/L course setup function did not work, period.  Restarted Exp, rebooted computer, both several times, and no charm.  Has always worked perfectly before.  Only change is update from Win7 to Win10.  The sea was rough and the mouse bounced around a bit prerace. Any thoughts on how to investigate or do forensics?  I can't get back to the boat to check the status for several days, so I'm in complete darkness. Thx, pjl
