after i used the "postflop diagram group with a stat" the color doesn't change anymore, but without using the group, only creating it in the configuration menu, the color changes automatically.
now its ok for me but a little bit buggy.
another bug only in the configuration/postflop diagram menu i have is, that the color picker closes automatically if i click on the color field. if i do it 2 or 3 times, then it doesn't bugs anymore for that one group. for the next group same problem again.
everywhere else the color picker works without problems.
