I should preface this by saying that I'm an extremely inexperienced linux user, and this might not even be an issue with ktorrent, but rather with some other settings.

I'm on a completely fresh install of Xubuntu, so I haven't even had much of a chance to screw anything up yet. I am on ktorrent 2.2.5 and I haven't touched any of the options in it except for port settings. I wouldn't even mind the problem if it weren't for the fact that I keep all of my downloads on an external hard drive, and it takes about 10-20 seconds before it is recognised, so when ktorrent starts up before the drive is recognised, it complains that none of my files can found, and I am forced to recheck them all. I checked that I am not saving my sessions on logout, and I checked that ktorrent is not on my "autostart" programs list.

Any more information that you need, I will do my best to provide.

Close Ktorrent before you logout/reboot
Or set KDE not to restore your previous session on login.

Hope that helps.

Thanks for such a quick reply Unfortunately though, that is either not my problem, or I am doing it wrong. I always close Ktorrent down when logging out/shutting down and uncheck the "save this session" option, and when I log in, I check to make sure that I am not restoring a previous session. I have also tried removing Ktorrent altogether and reinstalling it, but that didn't help either

Try do a "ps ax |grep ktor" in a shell window next time you have closed KTorrent and see if it shows up in the process tree before you logout. Sometimes my own KTorrent session hangs in the background even that I have no GUI left.

If the system tray icon is enabled and you click the X of the KT window, ktorrent will keep running in the background.

I figured out that the problem, apparently, was that I had two different versions of KTorrent on the computer without even realising it. One of them was the one that kept starting on login, and the other was a more recent install. Each time I removed the program, I was removing the one that was not starting automatically. I'm still not sure what the problem was in the first place, but it's all worked out now that I have removed the older install, so thank you very much for the help.
