Don't understand people having probs w/IE or windows anymore. I'm all over the place and the only reboots I ever do are after upgrades. The laptop is the only one that gets turned off. I haven't seen a blue screen or lock-up in years, since using UPSs. Even when it hogged the cycles I could still exit without rebooting. I'm just saying there's an issue here, that I don't experience anywhere else.
What really torqued me was spending an hour or so on text and diagrams and then have them disappear. Of course I still have the diagrams but the text is lost (and my motivation, too.)
