Hi willyb53,

Thanks for your help. My problem was that I was unable to open the Library Pallette. I have resolved my problem in opening the library through the small icon present top right of the room window (circles icon).
And for the Flash, I reinstall the last version of Medie Flash Player from Adobe through the window of Poser 9 revealed by clicking on Library, before I found the solution to open the Poser 9 Library Palette.
In have now the Library palette and I can go through the Poser 9 Library folders.
Thanks a lot  for your friendly help.
Robert
