Stuff like this happens to me all the time in Poser 7 (literally almost every time I use Point At with eyes). Mostly with child props and hair -- they seem to become unparented - they aren't, just Poser acts like they are. The only way I've been able to "fix" it is to close and restart Poser and they are all moving parented properly.
