Cool - I'll keep an eye on the forum. 

Nice to have a collective of minds and fingers working on a very weird problem.

One last data point - I also have a copy of Poser 7 on the same computer (just in case of goofy situations like this one) - and it works fine.  I don't know if Poser 7 and 8 use similar library mechanisms, that is whether they both rely on Explorer and Flash - so I don't know if this is relevant.
