I have found that under the FILE area that all the commands such as NEW to IMPORT to all the other commands causes a complete shut down of POSER 6, I relaoded my d/load, checked my drivers, I have a Nvidia Geforce FX5900XT brd and have not had an issue since day of install. I typed my happy fingers a tech-support email but do not expect anything in a reasonable time frame. Fells like a IN-COMPLETE D/load or In completed program
