Any key answer / active screen

[Guest andysalmon]

This one's got me stumped, I may just be overlooking a simple answer but it hasn't happened previously on my Magician or Vario before.

I carry my Vario III around in a large coat pocket for most of the time. I have a lot of appointments and calls that activate the screen when they occur. I then have the problem when fishing around for the device that a) I answer the call from touching the screen, :( End the call from touching the screen, c) Open a load of different apps where the appointments have made the screen go live and the movement in the pocket has brushed the screen.

All I want to do is use only the hardware buttons ie. Answer, End, Power button. Where can I find the settings for this? The "key settings" menu or "buttons" doesn't cover it so where is it? It's driving me mad!
