LW 4.12.6+ should resume incompletes but perhaps not if you updated afterward the problem of incomplete resuming started.

Reading your question is like trying to read back some of my answers. lol

If someone browses you then it is a type of search. Go to LW's Library window, select one of your shared folders. Then look to the right under Hits & Upload columns as those ones count. Hits are those files that have been seen in searches, Uploads are those that have been attempted to be uploaded.

When you share a folder & are connected to Gnutella then it will automatically create hashes for each file (may take some time for each file depending on its size), & be available to be searched on the gnutella network. If unsure, press the Refresh button which re-accounts for all of LW's shared files & folders. The refresh button should not be used too often though. Doing such can affect uploaders & also affect people's search results, & also use more than necessary resources for LW. It starts shared files from zero & recounts/re-adds them.
