I recently had to help an employee with his computer. He had to enter the admin credentials (like when you install a software as --> Run as Administrator).
I was unable to help him because although that prompt was loaded (see screengrab), I on my end could not see it. I was also unable to move the mouse as everything was blocked. It felt like I was "behind" that username/password prompt.
Is it possible to enter the username/password when I use Remote Utilities or this feature not available?
