When running the game at any resolution in fullscreen the mouse appears to be higher than displayed, having to hold the mouse a few hundred pixels lower than the UI element to interact with it.
Running in windowed mode fixes this however only at resolutions lower than 1920 x 1200
This is because you are using the wrong aspect or resolution.
Your monitor native res should be best but lower can look good too.
