After pressing enter immediately press arrow up and enter again a few times, this is a lot faster than doing the transactions manually in the Qt window. If the coins did not get through run quarkcoin-qt.exe -salvagewallet to save the coins and try a smaller transaction. A transaction can contain up to 160 prior transactions, so if you got many p2pool transactions of 0.1 qrk you could send up to 16 QRK at a time.
So suppose I have to manage a lot of transactions from a lot of addresses, this could be very annoying on the long-term no ? If there is a need to "reset" the wallet or making a script that involves splitting a transaction into a smaller chunk ?
Or it's just if A send to B, and there's less than 160 different "A" address, B would only send balance / sum(different A) ?
I don't really get this point... Is it really useful in the process ? Is there any way to get rid of that ?
