I thought I was going crazy!
I couldn't log in to my VM (Windows 10) via the remote console but I was able to via the browser console. Finally figured out that it's an issue with the modifier keys. In the browser console the shift actually works but control doesn't (so can't ctrl+C to stop running pings, etc.). In the VMRC neither the control key nor the shift key are working.

How can I fix this?

TIA!
