KTorrent 3.2.2 using KDE 4.2.4
1) I have several files on queue.
2) Click: Stop all
3) Click: Start all

KTorrent lost state of queue. After actions listed above all torrents not in the queue. And I have to add it manually. I think normall reaction for that actions is: All torrents which was in the queue will be in the queue. Active torrents was in the queue will be active in the queue.

And I think that state of queue must save until:
1) User manually add/delete from queue
2) Resume queue (by Start all)

If user want to start without queue all torrents you should do the following:
1) Start all. Queue starts from previous state
2) Select all torrents
3) Right click -> Remove from queue

But if queue don't save state the following situations is a big problem.
Manually do actions which is similar for saving state of queue:
1) Start all
2.a) Add all torrents to queue then manually remove each from queue. It's if torrents must be in queue great then torrents mustn't be in queue.
2.b) Manually add each torrent. Otherwise.
