Has anyone else noticed this? Start up Poser 8 (SR1) all library functions work. After one to over a dozen renders (maybe connected to the complexity of the scene), the library folders will have "?" instead on content numbers, you cannot add or delete runtimes, you cannot add anything from the libraries as the check mark and double check mark buttons are gone. Some folders will still show content, but double clicking the item gives you the "loading" message but will not load the figure, light, prop, pose, etc. Refresh does not work.

Now the odd behavior:
 

Click on the 'Content' tab, allow Content Paradise web info to load and go back the the 'Pose' tab and the entire library system is fully functional. This is repeatable.
