Original GitHub issue: https://github.com/debauchee/barrier/issues/949

Describe the bug
Barrier v2.3.3-release-3395cca9
The server is Mac 10.15.7 on a mid2014 MacBook Pro 15" i7
The client is Win10 Pro on a Lenovo x220 64bit i5
using Mac USB Keyboard with number pad connected to Mac

With the mouse on Windows screen, CTRL ALT Del has no effect using the USB keyboard

To Reproduce

Steps to reproduce the behavior:

  1. move mouse to Windows screen which has the message "Press Ctrl+Alt+Delete to unlock"
  2. hold Ctrl and Alt and tap the delete key
  3. See error

Expected behavior
The windows machine to present the login screen

Additional context

Once logged in, these keys work. This is possibly due to during troubleshooting i installed the Bootcamp Windows Keyboard driver.

I have no idea why - but this is working now. User error maybe... but I tried everything!
