Basically the main menu will re-show the default Roblox mouse if I made it invisible. But when a user clicks the “X” at top right of application to close the new menu Roblox has; the pop up doesn’t reenable the mouse like it should. This is a problem for games like mine that hid the mouse to make a custom mouse so we could have custom button hover images.

Gif showing the new Gui doesn’t:
To replicate (test this) just make mouse invisible. I made custom mouse by having an image moved to mouse location.
