I've used my x50v for over a month and a half now, and when i put little (like resting your finger on it) pressure on the case (no aluminium box just the pda itself) of the x50v on a specific place (marked red with FireworksMX in the picture :)) then whenever i try to tap the screen it registers a tap elsewhere. I think it's caused by my squishy screen that becomes softer when pressed from the side. When there isn't any pressure in that area, there is no problem using the pda. Hope this explains my problem, but i don't know a solution.... Is there a software way to do this (ie decrease screen sensitivity or something) or is it neccesary to open this baby up?
