I've just had a little adventure. I'm relatively new Kraken user and I've tried my first bitcoin withdrawal. Then I simply forgot that I have my bitcoins on a sell order. When I have tried to withdraw, I've got a bit frightening message "Withdrawals have been temporarily disabled for this asset. Please check back later." Of course I understand why I could not withdraw, but can you please make this message a bit more obvious like "You have no free BTC to withdraw"? I must admit I've panicked for a moment, after the Gox affair.

Of course when I realized the true reason, I simply cancelled the order, then withdrawn without any problem. As the sum was low, I've seen it in my wallet almost instantly, it also got 3 confirmations for now, so all is OK. Therefore I decided there is no point to submit a ticket, because there is no real problem, just some improvement suggestion from me.
