ForScore knows to check for ties. It will do so automatically when you print results or make HTML (web page) results.
Probably not of much impact to most of us, but in generating the 2008 Postal Match results WT had to click through 38 "there is a tie" warning messages each time.
Now, if there's more than one tie in a match you'll just get the number of ties displayed
If you say No, the Tied Results window will not pop up for this match again until you generate results for another match or restart ForScore.
If you say Yes, you'll see a list of the tied shooters.
