Quote - At first I thought it was my drivers, so I reverted back to an older driver but it still happened. Then I thought maybe it was the program so I re-installed.

You are not the only one, this has started happening to me as well lately and I've taken the same kinds of steps including reinstalling Poser and rolling back to an older video driver.  I'm more than halfway to thinking conspiracy theory stuff as to why it's suddenly started to be this unstable, I've been a heavy Poser user with this config for a couple of years and it was pretty well behaved until maybe this month.  It is stable under SreeD but preview is far slower than OpenGL :/
