Getting mouse movement while paused only working when mouse button pressed down

Having an issue here where I am attempting to get the mouse X / Y (basically to see if the mouse is being moved) while the game is paused. This is important for detecting input devices and changing the UI accordingly, such as switching between KYBD/Mouse and Gamepad.

Pretty much all inputs for it don’t work, unless I also press down a button on the mouse and move it around.

The same thing happens if you use the mouse events for X and Y, even when you tell them to be executed when paused in the details panel.

Am I missing something?

Did you figure it out in the end…?
I ran into the same problem…
