Strang problem with fire button

Windows has three buttons top right, the middle one lets you toggle between full screen display and user screen size. For some unknown reason the fire button will not work with the screen displayed full size. If I switch to user screen size it functions correctly. I’m running windows 7 on a HP laptop. I have not noticed any other buttons being disabled in full screen. Any ideas why this should happen?

Update to this problem. It is only effecting my windows 7 laptop. My desktop with windows10 is working fine. My poblem is the laser is setup and used with my laptop so need it to work correctly.
