It may have something to do with those 10dvc being the only coins in his new wallet, but even then why 0.5, so thought you might want to check."
I got 10 DVC from you and had no other balance. I have no voluntary payment fee configured for the client. The client demanded a minimum 0.5 DVC fee for the return payment. Hence, 9.5 DVC available and 0.5 as payment fee. See details of the payment here
Well either way for tx amount above 27k we would never see an issue, but I think tx's below that may not have been right according to the wiki... so I commented out the fAllowFree code which resets fee's for transactions below 27000 coins, so fees aren't reset back to 0 now...
Let's try it again and make sure its right according tot he original spec.
