I have an Adafruit 3.5" TFT running on an uno. I have it wired per the instructions on this site using the SPI interface. I have checked, doublechecked and then checked the wiring again, everything is according to the instructions. The graphic test example runs just fine for the screen output. The breakout touchpaint example does not work. It seems to load ok, I get the black screen with the seven color blocks to pick from on the side, but my touch is not recognized. Can't pick a color or draw on the screen.

This is my first time using displays so I just wanted to check if there is something common to look for before I start blaming the hardware.
