Right-click the search tab to "repeat search". With enough sources, LW can dl all night. You can find the most sources by using the more specific search terms (three words and the file extension works best for me).

Automatic requeries are pretty much forbidden on gnutella (they almost killed the network last year), and they are still crippling other networks. Clients (or 3rd party hacks) that use them run into "greedy client" filters which can mean others refuse your connection attempts or requests.

It's a very desirable user request, and so developers were *very* reluctant to make the decision to give it up. There may be attempts to find a way to do so in the future without harming networks, but not for now.

btw--the topic can still generate lots of emotion, so congrats on avoiding the flames!
