Mouse cursor disappears on UI operations

I’m creating a pause menu and I plan to use several canvas to show information to the user. I’m using canvas-enabled to toggle between canvas. The first time I press ESC it shows the menu and the mouse is there, but when I press a button that is supposed to lead me to another canvas, then the mouse cursor disappears and, as I have ESC key polled for controlling the pause menu, whenever I press it again it returns to the pause menu canvas. I’ve tried using Cursor.visible and setting a MouseLook mode, but even if the mouse cursor shows, I cannot move it.

Please, can you help me? I’m using Unity 5.5.

I have the same problem!
Did you solved it?
