I will add that Even if you are not using IE, you should keep it up to date and make sure you install the Flash for IE as well as your default Browser. Poser Library on Windows needs IE to be installed and it is best to keep it up to date. (IE 7 or Later)

And for weird crashes... check your Driver... Windows Updater has a nasty habit of rolling back Drivers with some updates... On Vista, I had to turn it off with my nVidia, because windows want me to install a Driver from 2008...
