Been thinking that the screen sensitivity on my 770 was getting a little awkward - taps on some parts of the screen weren't working particularly well, and this is after the girlfriends daughter had a go with Tuxpaint .... (my son has never caused problems with it - thought boys were harder on things than girls )

However, just installed Maemopad, and that happens to vary its pen size depending on how hard you press.

Draw with an even hand, and the line varies in width - therefore the screen touch sensor has been partially damaged ...

Is is possible to reset it, or do any other checks or repairs?
