How to prevent buttons from activating screen When I take my Android phone from my trousers pocket the screen is often activated since any press to the search, home, back or menu button activates the screen. Of course, this is a major battery drain. Even worse - sometimes the phone takes or rejects an incoming call while being in my pocket without me noticing. 8-(

So: is there any way to prevent these buttons from activating the screen? Only the power on button should wake it up, since it is much better hidden and cannot be accidentially pressed in the pocket.

In case that matters: my phone is a LG-P500 with Android version 2.2.2
If you did not find anything related in the settings, a solution could be to install a custom ROM (such as CyanogenMod). They often provide a much wider set of settings, and I remember having seen something like "Menu button wakes phones on/off" on some of my older devices.
