It shouldn't take long - you can select the whole skeleton group and attach that to the whole hand so it only needs to be done once. But... I've been experimenting. I used the spooky file on the content CD and from that I added a copy of spooky to my browser. I dragged this into a new file. It seems that if you drag a boned object from the browser and then attach the skeleton immediately while both groups are selected it doesn't attach properly. You can select spooky and move him away from his skeleton as in my pic. The solution seems to be to select all spooky's body parts by shift-clicking, leaving the group unchecked, then shift-click to select the skeleton group. Then attach the skeleton and all works as it should - spooky can't be moved separately from his bones.
