Report fixed: Stability Test freezing in Bug reports Posted February 10, 2017 v5.80.4072BETA. Running Stress CPU, after a minute and a half or so, the application stops responding. It does not crash, it is still running, but the GUI freezes. All other applications work fine while the Stress Test is frozen, no lag, no hesitation at all. I ran the Stress CPU using v5.80.4005BETA, 5.80.4028BETA, 5.80.4056BETA, and it worked as expected. Ideas?
