Thanks for your input folks.  As I stated before, my pc ran Poser just fine up until this latest reinstall of my system.  What I found was that I had forgotten to update my video card drivers after the reinstall (went to Nvidia to get the drivers and NOT let Windows Update find them for me), so I did that but of course, i still had probs with crashing, so i actually found a snippet at E-Frontier about doing a "clean" reinstall of Poser, which meant running my machine with a limited startup, uninstall and reinstall of Poser w/latest updates, reboot to normal startup and now, things seem to work just fine.  I think what the other prob was, is that before I reinstalled my system, I backed up my Runtime and I think something in my runtime was causing a conflict of some sort.  I didn't copy my runtime back to avoid issues but I did spend the greater part of my afternoon reinstalling content...what a pain the butt.  I ran Poser after I installed a "limited" amount of content, just to see what was up (some of the content consisted of the new V4.2) and things were stable.  I left my prefs at default, so i will do more trouble shooting this eve as in changing my prefs in Poser and installing more content.

Thanks again for the suggestions.
