Wolff this is the problem with using auto grouping and why most people prefer to group by hand in a program set up for it. places like gloves (fingers) the groups are so close that the autogrouping program in Poser some time gets confused and assigns some polys to the wrong group which causes it to look unwelded and create issues since those polys are trying to "follow" the wrong "bones". You CAN try to fix this with Posers internal grouping tool (You should read the documentation on this in the Poser manual). That should help with the gloves issues.

As for the wavy areas as ghost man said you have 2 options to try, use the weight mapping tool to smooth the weight maps in those areas. Or use the morphing tool to try to smooth the area with a morph. A combination of these two tools Should help with this issues. If not please send a couple of screen grabs, preferably on with a simple colored texture and the ground plane turned off, also if you could select the group with the waviness and open the weight mapping tools, in the tools select one of the operateions "exam: Bend, Twist, etc) so we can get an idea of where your weight mapping stands it would help a lot in trouble shooting.
