I'm going to have to chime in on this one as well, as I'm seeing the same thing as maxexcloo. Today, I've deleted the same files I've previoiusly deleted three other times because instead of deleting them from the other machine, BTSync seems h****-bent on recreating them on the machine I've just deleted them off of. I am sync'ing between a Linux and Windows 7 machine. The files were orginally downloaded into the Linux folder, sync'ed acrossed to the Windows machine, but then either moved or deleted from the Linux folder. Even the moved ones reappear, which means I now have two copies of these files in both locations. I am running 1.2.82 on both machines as well. I guess I could stand the delays as long as it did the right thing, but alas it doesn't even do that!
