Since the very first release of aMule I used, up to the current 2.0.0RC6, "First and last chunks first" never worked for me. I mean, I usually get the first chunk first, but the last one is often... the last. Even if it's not the last, it doesn't seems to be prioritized at all - quite the contrary, apparently. I think I already wrote about this here, and a developer assured me the function works fine, but in my experience, it never did, through the various releases. Any clue? Thanks.
