When I select objects (polylines, lines, hatches etc), I group them and when I try to select the newly formed group - there isn't a group. 

If I select them one more time to make a group, it says the group exist.. but its really not a group...  they are still different elements. 

Therefore, its really not performing that operation -- that is why I say it isn't working. 

Thank you for going in depth with that.. I really want to go to the bottom of it! 

Warmly, 

Mila
