PDA touch-screen failure at 8000 feet?
I use my Sony Clie TJ37 a lot, but rarely while flying. The other day I tried to use it at 8000 feet and the
touch screen was very unresponsive. I could *sometimes* get a click to register but I had to press very hard or "whack" it with the stylus. Back on the ground it works fine. Anybody have any similar experience, either GA or airline (cabin alt== 8000 feet)? I have heard of bad effects of altitude on hard disks, but it's hard to imagine such an effect on a touch screen! -- Cheers, John Clonts Temple, Texas N7NZ |

I'll have to climb high in the Bo and see if that does anything. |

No, my current iPAQ hx4700 and older 3955 screens work fine at 9000' (the highest I've used them in a plane). -- John T http://tknowlogy.com/TknoFlyer http://www.pocketgear.com/products_s...veloperid=4415 Reduce spam.

Had my Ipaq 5550 up to 13.5 a while back, no problem.

Probably tiny (invisible) air bubbles between layers of your screen. As you
decrease ambient air pressure these bubbles expand and push the layers farther apart. That's why you have to press harder to make an impression. Rod |
