When I get the blank screen no miners are running. Pressing keys doesn't refresh the screen. I will see if I can detect log file activity next time.
I have upload new code to master branch, It has totally new log system, please run and see log when you get blank screen again.
Much better! Thank you
BTW: The you need a backslash for /n :
NO POOLS!....retry in 10 sec
/nREMEMBER, IF YOUR ARE MINING ON ANONYMOUS WITHOUT AUTOEXCHANGE POOLS LIKE YIIMP, NANOPOOL, ETC. YOU MUST SET WALLET FOR AT LEAST ONE POOL COIN IN CONFIG.TXT
