When Director runs low on memory, it removes cast members from memory. Use the Property inspector to specify the priority with which a cast member is removed from memory. When a cast member is available in memory, it appears almost instantly. When the cast member needs to be loaded from disk, the loading can cause a delay. Set your cast members so that frequently used cast members remain in memory as long as possible.

These settings are the same for all types of cast members.

1. Select the cast members in the Cast window.
2. On the Property inspector Member tab, display the Graphical view, and then select an option from the Unload menu:

   3--Normal sets the selected cast members to be removed from memory after any priority 2 cast members are 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.
