Posterize Autopalette color confusion

Posterize Autopalette

1. load an image open Posterize and add a few colors
2. check the box Remap Colors and remap the alternate squares to other colors
3. click on Auto Palette button -> now if you on click the alternate squares their color pickers will display their paired square color instead.

Auto Palette and Refine Palette reset all the remapped colors since there is no guarantee the color they are remapping will not change. I did make the change that all open color pickers are closed when you do an Auto Palette or Refine Palette.
