Cant release texture memory using sprites

Hi I have a problem using sprites. I cant release the texture memory.

I have different background images with a slideView and I want to have a sprite in one image but when I pass to the next o previous image, I want to release the texture memory.

I used removeSelf() for the sprite instance and dispose() for the spriteSheet instance, but that no release the memory.

What can I do for release the texture memory? [import]uid: 43742 topic_id: 9102 reply_id: 309102[/import]
