I'm using Vue 8, my computer is 64 bit, 12 gig of ram, with an i7 processor, and yet when I'm viewing the preview window I often have my models reverting (albeit for short amounts of time and often when I'm moving the view point) to boxes.  The thing is, I don't remember this happening that often withmy old computer, which was significantly less powerful than my new one.  Is there something I need to do in the options menu to keep the models visible and not reverting to shaded boxes?  Hope this makes sense and that someone has some advice.....

Thanks!
