I don't think the problem is Limewire - I am using Limewire, Shareaza and Bearshare and experience similar results with all - I have used WinMX and Moprheus in the past and again similar results. I think it is the nature of the beast - you are at the mercy of the 'other guys connection speed and how busy their system is. Limewire's requery is simply another way to try and get a file that is not immediately available.
