I was using kmail on nahant and it was threading nicely. On FC3 it absolutely refuses to, and I _have_ compared settings. In Settings/Configure Kmail/Appearance/Headers I have x Show Attachment Icon x Thread list of message headers o Open threads that contain ... o Fancy format "Thread list of message headers" looks to me to be the one that does the trick, but it makes no difference I can on Nahant (threading works) or FC3 (where it doesn't). Any ideas? -- Cheers John Summerfield tourist pics: http://environmental.disaster.cds.merseine.nu/
