At last you're in command!

Sitting at your computer keyboard you can modify all the data for the match.

The main Compare screen now has an Edit button.

 

Click the button (or double-click the mismatched score) and you'll get a new screen showing exactly where the two computer systems don't match.

Click the Edit Local button to change the data on this computer or the Edit Remote button to change the data on the other computer.  (Or use the star and minus hot keys on the numeric keypad.)
