Histogram not staying on screen for more than a minute or two ?

[solentlife]

I have started using the Histogram to balance the peaks in the display ... and its fine but after a minute or two - it disappears ... only way to get it back up is to go to menu again ...

I thought it was supposed to stay displayed throughout all flight ?
