To Reproduce
Steps to reproduce the behavior:

1. Change resolution.
2. HASS.Agent disappears from tray and stops responding.
3. Restart HASS.Agent.
4. Everything works normally until you change resolutions again.

Expected behavior
Not crash when you change resolutions

Misc info (please complete the following information):

[rob-cohen]

I noticed that the crash only happens for major resolution changes.

[rob-cohen]

I also noticed that sometimes the crash happens spontaneously. Here's a log of the spontaneous crash.
The satellite service keeps running. Only the main HASS.Agent process crashes.

That's most likely fault of the VirtualDesktop library that HASS.Agent uses (related case #86).
Fixing it might be as easy as me adding a configuration option to disable all virtual desktop features or adding support for the upstream library for this specific version of OS that you have - which is not "that" easy.

[rob-cohen]

I don't think I'm using any virtual desktop features.
I'm only using CustomExecutor, Keys, and MultipleKeys commands triggered from HA.

It was working fine for me, but then I had to reinstall Windows and switched from Windows 10 Home to Windows 10 IoT Enterprise LTSC to stay on Windows 10 with MS support.

Eventually, I'm interested in trying HASS.Agent's Media Player functionality, but I currently only need HASS.Agent and those commands to work reliably.

Thanks!
