I keep mine running constantly, and it doesn't seem to have affected it adversely. Two things you should watch, ventilation and display.. A few times, I've had it closed and the display has incorrectly turned on, and evidently, the heat when closed it bad on the display, although it hasn't seemed to do any permanant damage, just looked washed out (very, almost unreadable) for an hour or so before it was back to normal. I keep it up on the feet so air can get underneath. I guess there is some dissent about this, someone on the list suggested that something hard like a desk is a better heatsink than air, but from usage, it gets hotter when it's flat on something, and especially if on something soft, like a lap or any cloth type thing. ____________________________________________________________________ jesse montrose <jesse@spine.com> http://www.hooked.net/bin/jesse.home After seven years, I was sent home to my family.
