When you create a color palette in the Color Palettes window or import a bitmap with its own palette, the palette appears in a cast as an ordinary cast member. You use cast member properties to name the palette and to specify how it is unloaded from memory.
The Color Palettes window appears.
Director makes a copy of the palette and prompts you to enter a name.
The following non-editable settings appear:
3--Normal sets the selected cast members to be removed from memory after any priority 2 cast members have been removed.
2--Next sets the selected cast members to be among the first removed from memory.
1--Last sets the selected cast members to be the last removed from memory.
0--Never sets the selected cast members to be retained in memory; these cast members are never unloaded.
