Mouse Pointer Issues

   I have been having an issue where, when I hover my mouse over the buttons in game and on the title screen and go to click said buttons it won't. It's until I move my mouse off the button to the side a bit does it then highlight the button and let me click without my mouse being on the button itself. I have a brand-new mouse, and everything's updated. I also haven't changed any of the settings either. I need a fix on this issue because it's really difficult to play when I can't click where I want to, normally.
