Thanks TrekkieGrrrl. . .was trying to keep on the bright side of things, I'm sure there must be a solution somehow.   I don't use Norton, but I do have McAfee, and it can be equally relentless in its pursuit of anything it suspects as intrusion of any sort.    It gives no option to disable during an installation that I can see.    And I agree with you, I don't "use" Internet Explorer 8 either except when absolutely necessary....my main browser is Firefox and for that reason I was hoping to not have to relax settings too much on Firefox.

I tried the little animation just to see what it would do.  The sunglasses on Andy were imported from another runtime as an object and darkened in Materials.   I'm able to open Poser Pro scenes... so for now that's the only way I can set up a complicated scene....which is better than nothing....or Andy would really be hanging his head...haha.

bagginsbill, I'm not sure if LL ever saw Andy on the opening screen.   He did appear, and still appears on mine, but that's all I've got.   As for LL's screen shot showing other libraries....after trying the method I posted earlier (quoted below), LL was able then to open scenes from Poser Pro and work with content....as I am also able to do, because the ShaderWorks script caused Poser 8 to "recognize" our external runtimes.   So....would be hard to tell if P8 is recognizing LL's other content on its own, or because of the help from ShaderWorks (see below).   I'm sure LL will be on later and could answer that.

QUOTE FROM MY EARLIER POST:   . . .since I had already previously set up external runtimes, and still have Poser Pro on my drive....decided to try the method I saw in one of the other threads, an animation at this link that shows how to get one of the python scripts to recognize all the runtimes on your drive....go here and watch if this stuff sounds a bit technical to you:

As you can see, part of what is being done in this animated demonstration is they are going up to scripts, partners, ShaderWorks, and then selecting import_runtimes...then it will ask something about "killing the scene"....which basically means it's going to force the program to shut down in order to make the changes.   Once Poser 8 can "recognize" all the external runtimes, then, if you have an older version of Poser still on your system, you can go set up your basic figure, props, whatever, just load it in any sort of way, save it as a scene, and then go to Poser 8 and open the scene and work with your content.   If you try to open a scene without running the python script, Poser 8 will ask to search for every single texture...and that gets old real quick....haha.   I know this is a round about way to get content into the program, but at least you can use it until a reasonable fix is established. ...
