Coby mp822 Calibrate! Heres how to Fix it?

i had hit the calibrate button and the screen went blue then went back to the menu screen but i couldnt use the touch screen only the buttons on the sides work....i hit calibrate again to make the blue screen come back on then i pressed the little square on the left top corner then the right top corner then the bottom left corner then it said success and it works great again!!!
