Full screen button

I don't know if it's related to gmaps or googlemaps api, but the fullscreen button on the maps does not work in 50% of time the maps is displayed. I have to put the focus on other objects on the page the refocus the map to make it working. Sometimes also this trick does not work and I have to reload the page to put the maps on fullscreen. Is there any way to check or debubg the click on the fullscreen button? Moreover there is a way to control if show the other button on the map (like the '+' and '-' to zoom and the 'Maps' and 'Satellite' options)?
