Touch sensing doesn't work with globes or overlay in LPC8xx

I did some experiments before I use the touch sensor in the LCP804 and LPC824 and the technology doesn't work with globes or thin overlays. The experiments were performed using the demo code for both boards.


Maybe I'm missing something. I've read (almost, I guess) all the application notes on the topic. What do I need to do in order to use the touch sense with overlays? Do you have real examples in which overlays or globes are succesfully used (real examples doesn't include the marketing videos)? Any ideas?
