My touchscreen isn't responding in the right places. Like when I touch the letter A in pictochat it instead goes to shift. And when I try to color the whole box in Pictochat I can't color like the last 2 centimeters in the right of the screen. This isn't only for Pictochat but for every game. When I touch something it doesn't work so I have to touch a centimeter to the right of what I want to touch so it will work. When I try to calibrate the squares just circle around. My DS lite has no scratches. And it was like this for about 1-1.5 years already and now it just got annoying. I really don't want to buy a new touch screen or anything is there any other solution. Also my L and R buttons don't work a lot. The only way to make them work I have to press it hard for it to work. When I blow it works for about 10-20min then I shut my DS off put it in my pocket and then when I want to play again the L and R don't work again and I have to blow again and it gets annoying.
