Somehow, a failure occurred in Poser 8 (blank library palette), after it had been working for some time now. It also took out the MAT file for a prop. Uninstalling Flash and Poser 8, obtaining the latest Flash, and reinstalling Flash then Poser 8 does not fix the problem. The problem may actually be outside of Poser itself. For now, I've reverted back to 'old reliable' Poser 7. This means the latest artwork I was working on I have to start all over in 7. There goes a few weeks work...
