The touchscreen on the CF-01 is unusual in that it rejects touches by a finger rather than the stylus. It must do this based on the spread of the touch I guess. However for use as a Touchscreen in some applications this is undesireable eg in my Home Automation application where I have a 6 x 5 grid of largish buttons with text.
The effect is that people think it is not working. Touching with your fingernail ( or the stylus) of course works fine. Anyone any ideas on how to get around this -? I assume the alternate caligraphy software offerings do not alter this 'built in' implementation.

This same issue has been driving me crazy for over a month. I have just about given up on using the CF-01 to control my Home Theater. It works great with a finger nail, but it doesn't respond at all to the finger. I hope someone has already found a solution. I've seen some posts about people using it to control X-10 devices, etc. So, what's the deal? Long fingernails?

It is my understanding that the touch-screen of the CF-01 is of the "resistive membrane" type. This means that a grid of conductors run horizontally and vertically and are held apart by a plastic matrix. The pin-point pressure of the stylus forces the two into contact, producing an input event. Thus the broad pressure of a finger is not detected.
A capacitance screen, OTOH simply senses contact, whether from a finger, or a stylus.
Hope this makes sense...
