version 3.1.1 b2679
System: Road Hog (stock, no wings, one DMX, USB memory stick)
I pressed "Open" and a cue number in the cue list window, many times. Eventually, I got a window titled "Wholehog (Not Responding)" with the message "8 editors already open, unable to open more"
At this point, the system is locked up. The sliders work, but that's all. None of the keys work. I have to reboot. When it rebooted, an OS screen briefly flashed with an error message, but went away too quickly to see it.
