12.75 Bug fix when reading some bridge files.

12.74 When creating PBN files: leading white spaces in tags have been eliminated and files with only one game no longer use the ## inherited value technique. Some updates to Hungarian translated have been completed.

12.73 An error in parsing results downloaded from BBO has been corrected. NOTE: Recently BBO has occasionally been overwhelmed with the number of users. As a result, downloading results from BBO may sometimes fail. Be patient and try again later.

12.69 This version corrects problems encountered when reading PBN files created by Jannersten's BOS program.

12.68 A few enhancements to the Total Score Table, ideal for viewing results from your duplicate club. Bulgarian and Swedish translations completed.
