When I mouse over Play the Exit button is highlighted. So when I click on play. It's actually clicking on Exit. If I hover over exit and click it will actually click on play. However If I alt-tab out and back in the game. while its launched and before clicking on anything. The buttons are selecting normally. Meaning, I hover over play and click on play and the next appropriate menu shows up.

This is also occuring in all menus. When I select Ra 1920x1080 resolution it does not go full change the size.

I got it fixed already. I just deleted my .cfg file in the documents and the screen resolution was finally able to be properly set and it doesnt have the issue any more.

Issue seems to have fixed itself.
