Very Strange ! It seems that you have all those problems because of Poser... But Poser and Vue 5 interacts only while Vue is reading Poser files. So there should be no problem whilw you work on Vue alone and Poser is closed. I have both Poser 5 and Vue 5 - Frequently they run together and I did not encountered such problems - Vue cooperates with Poser very well. I suggest you reinstall your Windows ! Are you running Windows XP ? I never experienced a System Crash on XP - sometime an application crashes but whole system crash ? Definitely you should format your HDD and reinstall the system. Maybe there is a mess in the Register
