Okay, this is not the blank library problem first.  Had that before, fixed it, no problems.

What has happened is that I began getting the infamous hang whenever I click ok joy.

So, since it happened before, uninstalled (with the unistaller) Flash, reinstalled.  Restarted, and I get:

Alternate HTML content should be placed here. This content requires the Adobe Flash Player. Get Flash

where the library should be.  Tried again.  Deleted all the librarypref.xml etc.  Nothing.  Try uninstall and reinstall and restart comp again.  Nothing.

I really don't want to reinstalling Poser again (would be the third time this month).

Any suggestions?
