 Added a "Set a default for new Session" option in the dialog as an easier way to set the default mode
AutoSave will not be triggered when a position is opened and no long analyze has been performed (to avoid overriding a rolled position file after is changed). |
|
Bug
Fixes |

Bug
Fixes |
Equity when Double/Beaver/Drop is now handled correctly
Can double pass 64 and fix a display problem in 3D for cube over 128.
Trice Count
- display of outside checker was wrong
- Roundup was not correct
Rolling out a position (or using a XGR level) when the player has won could yeld wrong results if the other player could win in the next roll.
After generating a Bear off database, it was not chosing it in the option dialog.
XG can now import game exported as text (at the different of MAT)
If the match was finished by a resign the favorite was not always display in the Match summary dialog
Profile level was displaying the wrong PR in the level graph for any other choice than "Display Weighted Games"
Save as XGP does not save Tutor information
Added a sanity check in a few rare Too good to double positions
Problem with positions marked for Batch rollout when the position has 32 moves saved
Using "Play from position" with manual dice could result in the game being stuck
Deleting a game from the profile that is stored with 2 different site only delete the entry selected.
When playing with an analyze level that has only a first pass with a level stronger than 3-ply and the computer analyze did not though the move was needed to be analyzed past 3-ply, the error was only analyzed up to 3-ply. Now the top move and move played will be analyzed in the level set for the first pass.
