I have a flaky touchscreen too, on a PW3. Sometimes it works for awhile, but often not. Sometimes pressing the power button off/on makes it work again for awhile. But then it becomes unresponsive again. Not sure what to do about it, so I leave it in USBnet mode so I can still use it for testing and development.
Also, a thread like this may get more technical assistance in the Kindle Developers Corner. Though you are not supposed to double post, so better to ask a moderator to move your thread...
