How do you properly deal with spritesheet removal with director class?

How do you properly deal with spritesheet removal with director class? I finally figured out how to free up the texture memory by diaposing of the sprite data; however, I am still having a memory leak and I suspect it is related to the sprite sheets. This because even though the texture memory is free on a change seen I am unable to save an edited spritesheet image when I am on a difference scene. This is not the case for images that I have loaded that are not spritesheets. Any thoughts would be appreciated. [import]uid: 79834 topic_id: 20530 reply_id: 320530[/import]
