S110 - any way to disable the touch screen?

I too will be interested in the reply, as I am considering the S110.  I have been using a Panasonic FX580 since June 2009, and as you may know it has a touch screen.  I haven't had any problems (at least not that I've noticed) inadvertently setting something wrong on the touch-screen.

Since you can always set the screen to black-out to save battery, you might consider making that setting for the minimum amount of time.  But then you have another problem if a fleeting opportunity presents itself and you're not ready.  To paraphrase my favorite history of science professor, "Ain't technology grand!"
