i applied both the ctrl+c and made the wait time longer, now it just takes longer to crash. I have found that i can manually "x" close t-rex with A.M. open and all is well, a.m. just sees it as a "miner not running" and will restart it. so its def something in the "stop" command causing the crash. Again, as long as i dont use a.m. to "stop" it, it never blackscreen reboots.
There is likely a small difference between the behavior when the mining software notice you close the mining console window compared to when Awesome Miner sending the close signal to the mining software.
I assume you run T-Rex as Administrator in order to get the LHR unlock feature. Do you get the same crash behavior if you uncheck the box for Administrator and also try with the Ctrl+C mode enabled?
I tried to uncheck "run as admin" but trex just errors out asking to be run as admin to unlock gpu.
