Hi Tina. try posting in the Windows forums http://www.gnutellaforums.com/forumdisplay.php?f=25 to get attention re the extra icon.

For the junk, just keep marking them as junk by using the little trash can. If too much junk keeps coming, use the File->Disconnect and then File->Connect to connect to new (and better) ultrapeers. They are the other machines that handle your searches, and if they give too much junk, they are connected to spammers.

Currently, the devs are working on making that better, so watch for updates.

Re adult stuff, lots will get through no matter what you do. However, you help by adding keywords to the Options->Filter->Keywords. This way any result that has the term you set won't show in your results.

For now though, the most efficient practise is still to use common sense and ignore results that obviously look bad. After a while I don't even notice the junk

cheers
