I've already answered to your blog comment, so let me quote my message for your convenience:
Hello!
I just tried to test RPC Wallet.
I so sad to inform you about errors in current version [PaymentService v1.0.7.564()].
I use Windows version.
First of all it doesn't work as Win service. At all.
Second issue is much worse - amount of money sent to wallets does not equal amount received.
So I advice everybody not to use RPC Wallet at present time

Thank you for the feedback.
First of all, the latest version of RPC Wallet, which is available for download on the website is v.1.0.8.1.614().
>Second issue is much worse - amount of money sent to wallets does not equal amount received.
Could you provide more details? Do you mean that let's say you make a transfer for 1000 coins, but the recipient gets another amount? Or is it your issue that the transaction in the block explorer shows higher amount than you were sending?
The second case is a completely valid CryptoNote protocol behavior. When you send a transaction, it further conceals the sum by increasing the original amount. The difference is returned back to your wallet as an unlinkable change.
>First of all it doesn't work as Win service. At all.
What is the Win version that you are using? Could you elaborate on the steps you made?
