If it was a flaw you would think the other programs I ran would be affected also, which they were not. Dreamweaver,flash, photoshop, paintshop, intense gaming, earth and beyond, daoc, eq, not to mention bryce and the game developement software we use. Well either way I reformated it back to the NTFS and it still wouldn't run. So re-reformated (is that a word?) and used the fat32 and poser hasn't crashed once on me since then. I care not what fixed it, just know I can access Poser again and that is good enough for me. Thanks for all the input and help from everyone. A great group of people. Safe journey and blessed be Myl
