Both blocks 38304 00000000015bb4069249fa1f41ae61d8a7447aaacc33c50dacd3c3654377fa43
and 40320 000000008011f56b8c92ff27fb502df5723171c5374673670ef0eee3696aee6d are difficulty transition blocks. However, block 40320 has a difficulty of 1. I know there is this special testnet rule that allows mining a block at difficulty 1, but I always thought you can't use this exception on difficulty transition blocks. As a result, bitcoinj based clients do not advance their blockchain past block 40319. ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
