v. 1.5.6 still have problem - if some gpus stop hashing the miner not hangs but just stoped and not showing any information further. So if i see that and press some key (space or h for example) it will show that gpu's hash speed is 0 and make reconnect to pool and after it will work good for some time.
sorry but i dont understand,can you turn on logging and share that?
i asked this days if you know the developer - i tried the programm and it works now (with threashold)
it checks the miner and you can set a threshold - the miner restart without a problem if there is no hash (miner stopped or hanged) or low hash
