hello...i have been attempting to teach myself this program and there is one major problem that i'm having...let me know if you can help. When I group numerous objects together (to have a final product)then want to ungroup the object to do a few touch-ups, the program doesn't allow me to do it. I have been using the connecter line tool and the pen tool mostly. If anyone knows how to get by this simple task please let me know. thanks.
