I used to follow the reinstall windows every so often philosophy, especially before XP came out.  But after reinstalling XP 5 times in one week and 100's of GB's of software (due to an impending hardware failure that I finally diagnosed after the 5th load), along with reregistration, entering software keys, etc.,  I swore I would never do it again.

I picked up JV 16 Power Tools (not free) which is a suite of tools.  I use the Registry Cleaner the most. It is amazing how many useless and obsolete keys, file pointers and other junk build up in only a week, especially if you copy, move and delete a lot of files, install and uninstall software.

Adware, spyware, etc, in my opinion, fall into a different category, with their own tool sets for prevention and removal.  I used to use Norton on my ME machine years ago, and it saved me from a trojan horse, once, but I still had to go into the registry to remove the final traces that Norton couldn't remove.  I now use a different strategy, with tool sets for both general maintenance and special maintenance.

I routinely clean out my working folders, run registry cleaner and then defrag my hard drive every week or two.  That with having disabled all windows services I don't need has kept my 'puter running lean and mean for over a year since I built it.  I consider this general maintenance.

I've seen similar problems, although I haven't tried every new feature.  Mysterious crashes where P7 just vanishes.

I was in the setup room deleting bones to setup a a clothing set and ... gone.

Opened V4, applied a high res mat and one of the eye surfaces is opaque.  Can't see one of the eyes. Renders fine, but rather annoying to look at while working.  Doesn't happen in P6.  And I have repeated it several times with the same results.

On the other hand, the new mesh morphing tool seemed to work ok. It's handy to directly modify the mesh from within Poser.

Girl3 is par excellence!

I too would appreciate trying her out. Thanks for your work here and on other projects.
