Hmm. I've had P5 installed on my 'dedicated' PC since it was delivered at the beginning of the year. This PC only runs graphic apps, nothing in the background, no internet, no email, nothing beyond CD burner and graphics drivers loaded. It's an AMD 1.6Ghz under W2K. A while back I noticed that it was sometimes reluctant to load up saved scenes and would go into a sulk. Today, I've tried to load it up and it just doesn't happen. If you look carefully you can see a window load up and then it just disappears. I've tried reapplying SP3, I've tried moving my runtime elsewhere and reloading P5 from scratch, still the same result. I don't think that I've done anything out of the ordinary since last time I used Poser, no new software or anything. Anyone any ideas? Ta Dogsbody.
