I went back to 1.69. This version has regressed. I finished work on one of my extra clients on a remote computer for the Formula BOINC team competition so I told the client, through BT, No New Work. It still got new work. I abort it. It got another. I suspend the whole project and BT still got another. Projects sidebar had it as NNW and Suspended but there was a WUProp task running anyway. There is no other BM controlling that client besides BT. Back on 1.69 suspending the project properly suspended the task.
