How to clear invalid transactions from one's wallet? I've recently been testing double-spend attacks against myself using a couple wallets, and the standard client does not appear to clear conflicting transactions from its transaction list, even if the other ones have already become a part of a block. How do I get rid of invalid transactions from my wallet?
This question was answered before for someone to clear a too low fee transaction that wasn't accepted by the network. https://bitcoin.stackexchange.com/a/2415/1461
