Okay, let me get some screenshots going here. What I saw was a LibraryState.xml. When I opened this in word pad, it turned out to be a history of activity I had done with Poser that day. When I read through the entries, I recognized actions I had done with Poser. This probably isn't meant to display in IE so I paniced over nothing. After editing the Libraryprefs.xml which had two wrong paths in it, the Library palette displays in Firefox correctly. But of course since I added the Poser 8 directory again manually, I have two entries for Poser 8 and I don't know how to delete on of them. I have only gotten the library palette to display under IE once.
