I have a computer that only runs a couple of hours a day. On it, I have a problem of work units having sufficient time to run and report before they expire. Part of that problem is that BOINC always wants to have at least one work unit in the queue, in addition to the one it's working on. That extra unit or two sits there for days -- eating up expiration time -- waiting for its chance to be handled and reported by the agent.

In my Preferences, I've tried setting my Additional Work Buffer to zero, but it still downloads new units days ahead of time. What else can I do. I wouldn't even mind having to take charge manually of this process if need be. But I just hate having my little computing time wasted because it's aged too much in queue. Thanks for helping.
