I think I may just have to bump up the OS. I checked the temp of the CPU and it is holding steady between 125 and 128...not sure if that is too high or not. I'm not so sure it is a heat issue as the temp is about the same when I have say Dreamweaver or Photoshop running and I am not experiencing any probs with them. A friend of mine said that the problem could be linked to a file called Tpkd.vxd. Anyone have any info on this file and how that could affect Poser?
