Thanks Don, for your prompt and thorough answer. I'm curious if anyone else has had the problem with the brightness being turned down. It's strange that both my wife and I have experienced the same problem. For a while I thought bright light on the screen (i.e. sun) might be the problem, but I've had it happen other times too and so has she.
I use a password every time I power up, but not for every phone call. I'll have to live with it, I guess.
What are you calling an unattended system backup? Is that using Blue Tooth to synchronize the device with the PC? (I haven't started doing that yet, but I intend to.) Otherwise, I simply trust that the ActiveSync is a good enough backup and that works whenever I plug my handheld to the USB port.
Thanks for the suggestion to switch to another program like Notes when I'm listening to something that I don't want to be affected by inadvertent pressure on the screen. I think I will do that.
As for Flight mode, I've found that my phone sometimes drops into Flight mode without my intending it to do so. The worst problem with that is that I've sometimes missed calls without realizing it and I'm less than perfect about checking voicemail regularly. At least the phone shows the "notification" tag when I re-activate the phone.
I do love the device. It pretty much does everything I need. My wife isn't so sure. She finds it a bit more complicated than she'd like.
I do need a program that will allow me to shut down programs instead of leaving them on when I switch to a different program. I believe I saw references to this in previous posts, so I'll go back and research it.
Thanks again for your help.
