thank you both for your help , i cleaned it even though i couldnt see any dust.
I have found it works if i press it a lot 5-6 times maybe to register a click , unlike the back button which just works easily like a touch screen phone first time.
anything else i could try?
When i click that area of the screen to change a page during reading a book it works so it is not as though it is a dead area of the screen, could it be a bug ? this is 3.3.0 software ..
Or is it user error , any other ideas
