Heh! I wish I COULD ctrl alt del when Poser freezes on me! My lock-ups are so bad that the reset button is the only option. E-Frontiers does suggest reducing the acceleration settings on a graphics card if you're having lock-ups, and I tried it, but after I did, all the checks, pluses and minuses beneath my libraries disappeared. The only way to restore them was to re-install P5. Grrrrrrr!
