Freeze / no response when trying to see status or output, most of the time

[sona1111]

Hello, I have a question / problem with HC on windows10. Using with five RX570 gpus. I am trying to run a dictionary+mask attack on wpa2. Usually this process takes about 4 hours. Sometimes, I am able to reach the end and see the result, but more often I get no output after the "Status[S] Quit[Q] etc" section and pressing "s" for status or "q" for quit does nothing except show one extra newline the first time the key is pressed.  Also, sometimes this problem shows up right when I start the process (pressing "s" shows nothing), while other times a few status messages work in the beginning, and then somewhere between then and the end it will 'freeze'. The logfile also does not show any more information after the 'freeze'. Furthermore, the actual cracking process does not seem to freeze, as I always note that the GPU fans will spin down after about four hours. Its just something about showing the output that is an issue, I guess. (?) I have also tried with -w1,2,3,4 without any noticeable change. Also, I have tried restarting the PC in between most of these tests. Are there any more efforts I can try to figure out what is going on? 

The dict is 10926977 lines, 171.6MB, and the mask is three digits, right side. 

Thank you for reading.
