Interrupting Loader

I have a problem where I’m trying to load a different section of an XML based gallery, while it is still loading up another. It loads the gallery, but every other of the thumbnails return a height and width of zero, which is obviously wrong. I have tried closing the Loader when theres still a gallery loading (Loader.close()). I have tried all day trying to think what could cause this error, but have come up with nothing. I reset all the variables once the gallery is loaded. I there a good way to interrupt the Loader? :m:
