I was running an old bitcoin client from february or something, but decided to update today (0.3.24-beta). Then I sent some bitcoins, and I have transaction fee set at 0.00.
Then I get this:
Debit: -25.99
Transaction fee: -0.00133919
Net amount: -25.99133919
Are transaction fees mandatory now? How is the amount calculated? It would also be nice if the send coins dialog warned me of this fee BEFORE I press send.
That's a bug in the 0.3.24 client and I believe it has been already fixed.
