The coins have 30 confirmations, so they're not old by the net standard. I still don't understand why MyBitcoin.com can send minimum amount for free and I can't.

Hello,

I'm trying to send 0.1 BTC from the official client (Version 0.3.21 beta) but I get an error message suggesting (or rather forcing) me to pay 0.01 BTC for transaction fees since the transaction is over the size limit. I find this strange since I can send this amount from MyBitcoin.com without a problem and furthermore the wiki states that only transaction less than 0.01 BTC or bigger than 27 Kb should incur transaction fee (https://en.bitcoin.it/wiki/Transaction_fees).

Can anyone explain this error message?

Thanks in advance,
Mosh.
