Is anyone else having these problems?

If I add one of the tail ends (the full mil. dragon, haven't tried it with the lite) it attaches itself to the dragon where it should be. As soon as I pose the tail, or use one of the poses that were Daz freebies this week, the tail end detaches itself - in fact stays where it was originally when the tail moves on. Pose the critter first and then add the tail? It never gets anywhere near where it should go. The trans, bend and twist dials seem to behave in a very strange way when you are trying to reunite the tip with the rest of the tail. Bend was behaving exactly as I would expect x-trans to behave, and vice versa. Once I got the hang of the fact that you need to use the 'wrong' dials, it all came together quite easily. But there seems no way to set the main figure as parent to the end of his tail, nor any other way of keeping them together if you tweak a pose.

An added problem is that the spade tail causes Poser to hang if I try to use it. I have to close it down with CTRL/ALT/DEL, and sometimes I have to reboot before being able to launch Poser again without an 'illegal operation' message.

Are these bugs in the program or in my installation, do you suppose?
