the claims that the problems with limewire downloads are just due to network traffic jams are nonsense. that doesn't explain why the latest version of limewire suffers from so many more failed downloads than previous versions. the message "requery sent" seems to mean nothing as far as i can tell. the download almost never resumes.

but, there are a couple of things that seem to help with the requery bug:

1. set your preferences for only 4 star results. (i know other people have said this, but it's true.)
2. when you get the requery message, try doing a "repeat search" command. you can find it in a pulldown menu by command-clicking on the tab with the search terms in it (mac). this often resuscitates the dead download. it makes no logical sense, but it often works.
