This has revealed a problem which I was wondering if anyone else had noticed. If I select just ONE of the completed torrents and start a recheck, suddenly the deluge screen removes all the torrent information about all the torrents then freezes. If I check conky I see that the deluge has completely frozen because net activity stops. So I have to kill deluge and restart. It always takes 3-4 restarts before it does genuinely restart properly (title bar saying Deluge and a completely blank window). When it does restart, every actively downloading torrent has started rechecking itself one after the other. Given that some are 4-10Gb, this takes ages.
So it makes it challenging to force a recheck of just the one that has completed - it almost always leads to a lockup, multiple restarts of the client, and a foreced recheck of ALL the active torrents

Anyone got a workaround?
