It's a good idea to uninstall and then reinstall flash after an IE update. My Poser library worked right out of the box until Smith Micro released the bug fix. After that, I needed to download the latest version of IE and reinstall flash before things worked properly. 

I think it was a mistake to have built the Poser library on the soft and shifting sands of Microsoft IE and Adobe Flash, but maybe it will force the users to upgrade more quickly than the Poser 4 fans since the continual updates of third party components will make Poser 8 unusable in the future.
