Salut, most of the time this behavior rotating queues come from the servent named shareaza. Be sure to look from wich servent you are dling by looking at the servent column (you can enable it with a right click on the cloumns bar). If you want to tell them about it (why it confuses users, no improvement) go to their forums. (to their defense, they introduce large files that wouldn't be there otherwise).

Bonne chance
