I have an 5 year old iPod 4G 20 GB I've recently been wanted to use again. The problem is that the click-wheel is not nearly as sensitive as it used to be. I've learned that it's due to the lack of sensing the capacitance from my finger. This can be temporarily circumvented by touching the wheel very, very lightly (this gains the capacitance between the wheel and finger apparently). The click-wheel stops responding every time a click the buttons (except when clicking really quick). So I have to turn the hold-button off and on (this seems to somehow reset the click-wheel's sensitivity) I don't think this is durable in the long run. Has anyone another fix to this problem? Maybe a hack, so I could use the forward/rewind-buttons for scrolling? Any suggestion is welcome!
