2.4.2 - If you gave a name to a race that converted properly into a number, for example "1" or "123" then when you tried to produce a "Corrected Time" report, the program would crash. Now no longer allow naming of races with just numbers, and when you open a previous regatta that had race names that were just numbers, the name is prepended with the word "Race ".
2.4.1 - When you produce an "Overall Results" report, individual race results are not produced if the Starting Division type is "One Design". It's just not necessary and takes up a lot of paper.
