Using the original FW .6, I had some problems with BT (deleted Tasks wouldn't go away if I chose deleting Task & Files - after which the Tasks stayed stuck no matter what I tried).
I updated the FW to the beta 07.2 and that got rid of all the previously deleted tasks though I didn't dare to attempt another Task+Files delete.
Don't see any thing else differently other than what mentioned above. Also, my internet connection seems to be dragging really slow if there are BT tasks running. Stopping all the tasks would bring the speed back up - I suppose that's what the download scheduling is for so that download can be done during off-peak hours.
that is good news, I have three tasks stuck in my downloadmanager, the problem seemd to be that is in the name of the torrent file there would be an ' (don't know how it is named in english, lol) the torrent file would be impossible to get rid of....
