Crosshair is offset depending on window size?

So basically what this does is just that there’s supposed to be a crosshair tracking the mouse, but then it offsets depending on the window size?? I don’t know how to explain it, it’s weird.

Maybe “counter” offseting the crosshair depending on the window size back to the mouse would fix it. I want to make it so the crosshair is actually on the mouse and not offset.

Have you got the anchor points set at 0.5,0.5 and place it at 50%,50% ?

If you haven't got the anchor points set it's the easiest way to fix the problem! :) - if you want things to scale use percentages not offsets for your position :)
