i went into big screen but can't reach any of the buttons on the bottom right to go back into small screen or walls radio active ect.... i have a mac and the green button that you can minimize with isn't there. i tried reinstalling and that didn't do anything and i tried closing and reopening and going into window at the top and going into the options on the dock and i also tried using the top left corner for dragging but it didn't work. any suggestions please
