It seems darksend doesn't work when a bunch of your coins are locked. For example I have the bulk of the coins locked and the remaining can't be mixed. This is the message I keep getting: Also the message should be changed. Even when it's working you get this "Darksend is idle" msg and and "Time out" msgs which give the user the impression they are error messages. These messages need to be changed to something like "Please wait, mixing will take a while. Estimated time...".
