Help! Help! Oh, Help!

Okay, all you electo-mavens out there. My beloved Palm Tungsten T5 is making my life a living hell. For some inexplicable reason, my screen no longer responds to the stylus. I can maneuver around the screen by pressing the buttons on the bottom of the PDA, but when I touch the stylus to the pressure-sensitive screen to input data, or highlight something or whatever, nada. No response. No reaction. Now, I've already tried resetting it repeatedly to no avail, and I've cleaned under the rim of the screen with a business card in case something was pressing on the screen under there. Again, no reaction.

So, please, if one of you out there has any idea how to fix this sucker so I don't have to buy myself a new one, please let me know ASAP. I'm tearing out what little hair I have left.

Thanks in advance for whatever help you can give.
