user7441: Any one can explain me why I get a negative balance after execute a sendfrom ?
"sendfrom myaccount btcaddress amount"
and right after
"getbalance myaccount" return  a negative balance
I don't really understand why the balance is negative ...
After 1confirmation, the balance come back to his real value.

Yes, that is a 'WONTFIX'.
A sendall account  command that took the account to exactly
  zero might be a good solution, although you can still run into edge
  cases like "what if the account contains 0.000001 BTC" (fee to sendall
  might be greater than that).
