I was trying to help and allow for just another possibility. People do enter stuff into the wrong forums accidentally ya know. I have!
I'd say you've got a setting wrong if you have to hit the power button when you get a call or a text. Like I said, I've never had to, except possibly if I had a buggy app crashing at the time or something, but never that I can remember. And that's on my A855 "droid", not rooted, only Verizon OTA updates. I do run an app called "missed call", and another: "App Alarm Lite". I've used "native" SMS and Handcent. Never have to hit the power button. The droid display turns on, lights up, ringtone plays, vibrator vibes, and I swipe it, or enter a reply SMS and tap "send".
you're darn right about it being nice to have an option or setting though.
