Download DD Solver Version 12.85c

Results from BBO for multiple months can now be downloaded.

12.85c Fixed a problem with the inability to use the Filter.

12.85b Fixed problem with score when MP hand was passed out. Two more months added to BBO downloads.

12.85a Fixed problem downloading BBO results on passed out hands.

12.84i Fixed a long standing problem with time zones when downloading BBO hands.

12.84h Fixed a problem when bidding alert had unbalanced quotation marks.

12.84f Fixed a problem when downloading Match Point results from BBO.

12.84e Fixed a problem when merging multiple files.

12.84d More Team Scores bug fixes

12.84c Parsing the Team Scores results for the 'closed room' required a small fix.

12.84b Fixes a problem when merging multiple files. Now that BBO only allows downloading from the most recent 14 days it is even more desirable to merge multiple files. For example, assume you ("BBOstar") have downloaded two different periods and have two files: BBOStar 2020-05-30 to 2020-06-04 and also BBOStar 2020-06-01 to 2020-06-07 . If you want to merge these two files,  click Open File, hold the <ctrl> key down while you select both of those files. Then click Open (bottom right) in the open dialog box. You will see a brief summary of the files selected (file name, deals, date of the last hand, and the bottom player for that file). You will now have a chance to rename that merged file. DDS will also let you delete all deals that appear multiple times in the new merged file.
