I just did a few tests and I have tracked down one issue and it looks to be with Flash.  There is a new update and once that is installed the Poser 8 library tries to open but only opens part way.  I don't use Air so I don't think that has anything to do with my issue at least.  Running more tests.  Why it works in Poser 10 and not in Poser 8 leads me to believe that there is something different in the Poser editions, so what is different in Poser 10 then 8 concerning Flash.  Happens on both 32 bit and 64 bit
