I'm still getting the same messages on BOINC Manager and nothing else. They occur every twenty minutes or so, but the progress bar does increase, so I'm not sure that there's any problem now.

As far as I can tell, my computer keeps the correct time, and I can't find NTP on it. What sort of messages should I be getting, though?

Thank you, but I've already synchronized the time. It's still possible that that could be the source of the problems, though. I occasionally see the time to completion field moving backward, though that's generally not uncommon, in my experience. Since I installed BOINC Manager five days ago, the progress bars have filled to 41% and 34% (keeping in mind that my computer hasn't been running the entire time). It all looks like it's in order, but when I click on the messages tab, I still see the 'zero status' messages. I simply don't know whether or not it should be telling me something else.

That wasn't what I meant. There are two progress bars; one was at 41% last night and the other was at 34%. Right now, they're 42% and 36%. (I was away for most of the day and didn't have my computer turned on.) Still, I do occasionally notice the progress dropping a bit, so I'll see if it's a problem with the time. I can't disable automatic time sync, though, because that option doesn't seem to exist.

I synchronized the time with another clock, and so far, they've stayed together. The progress does still increase, but every once in a while, I just get that zero status message. If I allow it to keep going, then I can only assume that the progress bars will fill, and when they do, will these errors be a problem?
