thank you so very much, i'm back to normal. btw is it ok to always leave it plugged in when i'm using it? & also would you say that the screen froze? i'm not sure if by pressing & or holding down buttons switched the screens. i thought i read that you can make the tablet side on the left or something like that. this is all new to me. i updated it last night & it says dingo 1.9, firmware 1.6. is that where it should be at. thank you very much once again.
