In my Poser>Window menu, I see this:

The tick next to the Libraries item tells me to expect the library palette to be visible, somewhere. What does yours show? I ask, since the Library Palette may be docked or floating, and if it's floating, it's possible that it could be behind Poser's main window. Dragging the corner of Poser's main window might reveal the library, if it is visible and just hidden behind, but we need to establish whether it's supposed to be visible at all, first.

[Edited]

Actually, now that I look closer, you have the docking icon and refresh arrow circle at the bottom right that implies that the library palette is visible, but empty. Strange.

What happens if you click the refresh arrow circle at the bottom right?

Also, what happens if you undock (make floating) the library palette via its top, right dropdown menu? Does it show anything different. Can you resize it when it's floating?
