12.86q This version corrects a problem in Team Scores.

Many users have experienced problems downloading results from BBO - probably due to download speeds. The error occurs when you try to save the file before it has been completely downloaded. After clicking Get Results DDS starts downloading an HTML file called BBO.ddb to your Downloads folder. In the bottom left corner of your browser you should see this:

with a blue circle around "BBO.ddb". If that circle appears to be moving around, it indicates that the downloading process has not completed. Do not click on the Save button in the Save file as... dialog box until the movement stops, a few seconds after you've clicked Get Results.

If you happen to click prematurely, and get the error message, you can either:

  1. Go to File -> Open BBO.ddb file in the main menu and click on the BBO.ddb file in your Downloads folder, OR
  2. Try again, making sure to wait until the blue circle has stopped moving.

12.86p The Scoreboard now allows you to filter by calendar year. This is especially beneficial when you have a large SQL file that spans many years.

12.86o A few enhancements to speed up the program.
