Thanks birdy!

I had thought the junk symbol was based on what other peple had marked as junk (I had just downloaded LimeWire after a Windows reinstall, and a few weeks after last using LW, which was a previous version and none of the files were repeats of what I had downloaded before - I just assumed others had marked the files as junk). Now after quickly glancing at that thread I just relised that there is a Junk Filter in the Options of LimeWire - I never even knew that and I've been using LW off and on for a year! It's the first time I've ever noticed the junk symbol appearing in the search result, I can only assume it's linked to the version of LW I'm using (4.12.1, I think my previous version was 4.10.9 or something similar).
