Also if you find that you've lost your groups - either through export/import or due to subdivision quirks in whatever app you're using - you can get them back by loading your morphed figure into UVMapper (I think this is in both Pro and basic) and then choosing Import UV's from the UVMapper file menu.  Select the original unmorphed base as the file to be imported. This will overwrite the groups in your morphed figure. Then just save it out under a new name. Easy. :)
