What rate of not-accepted did you see? I didn’t see anything unusual on my end. If you had more than, say, 4 in a row, that would be abnormal and probably a loss of network communication. If it’s scattered and less than 25%, just random bad luck. It’s normal and harmless to randomly get some per cent of not-accepted, and of course randomness can sometimes bunch up and look like a pattern.

This was the odd run (shown in context):

It could be loss of connectivity, though I wasn’t aware of it at the time.

The idea of an option to View/Hide unaccepted blocks is a good one, as well as View/Hide all generated blocks so you can more easily see incoming transactions. Seeing the unaccepted blocks is just annoying and frustrating. Everyone faces the same rate of unaccepted, it’s just a part of the process. It would probably be best to default to hide unaccepted blocks, so as not to show giving and taking away something that never was, and not show new generated blocks at all until they have at least one confirmation. It would only mean finding out you have a generated block 15 minutes later than normal, and then you still have 119 blocks to go before it matures anyway. This is on the to-do list for v0.1.6.

Sounds good to me. I assume you still have plans for multi-processor support.

I’m having an unusual run of failures, and thought I’d let you know in case this was of any significance.
