canon 6D rear screen viewing duration

[Kidkodak]

Hello I am new be with ML and I have a basic problem. Unfortunate the english are not my best language I am sorry about that.
I am using a 6D with ML last version, when I try to set a adjustment the screen disappear very quickly.
I set the camera to having a long viewing but no result. Is they have a setting in ML to giving me more time to look the screen?
Thank Kidkodak

Nope, some bug in ML (on the 6d).
But as long as you press buttons, the menu stays visible, so keep on pushing buttons 
Maybe use up and down while looking into menu's.
