Armoury Control Crashes Shortly After Launch

[smreichling]

I'll launch Armoury Control, I see its icon pop up in the taskbar for ~3 seconds, then it crashes and the icon disappears.

The exit code is 82. I'm running the latest version (0.0.7.3).

This seems to happen specifically when I have an external display attached to my laptop and the built-in display is switched off. If I switch back to using the built-in display, I can once again launch Armoury Control successfully.

I poked around in the Windows Event Viewer and found this stack trace from the crash:

Application: Armoury Control.exe
