I'm totally puzzled with this one. You have not answered some of my questions, so it is hard to make a really accurage diagnosis there. What about the printer? I've gone back and forth between cable, dialup and dsl internet, and Poser has never been affected by that. It would likely be a mistake to try installing another copy of Windows on another hard drive on the same computer. In some ways it sounds like you know advanced stuff, then in some ways it doesn't. Sometimes it's dangerous to try things that are perhaps beyond your own abilities or knowledge. It is really hard to judge such things when you rely solely on forum messages. I wish you the best of luck. It sounds like this is one time I haven't been of much help.
