Ah, ignore that question, Egg. I re-exported the pages and everything is working fine (I don't know what's changed, but at least it works!).

However, another question. I want to put some arrows onto the slider so that the user can move to the next "page". I've done this successfully, but the problem is that as the image scrolls out (I'm using the wipe left transition), the arrow buttons do, too. Is there a way that I can keep them static and only have the "content" of the slider page move?
