Hi there,
 
I begin to use pyMol recently.  I got two problems:
 
1. for some reasons, the (sele) object disappeared.  I could not highlight the selected residue after I selected one or more residues with dispalying sequence.  Instead of show some dots (selected atoms), the selected residues were turned to be stick mode.  I believe I misclicked some option and could not figure out how to click it back.  This is only existed in the current session.  If I open a new file or session, things go back normal (or default).
 
2. the hydrogen adding for ligand aromatic rings is wrong.  PyMol treats aromatic carbon to be sp3 carbon when it added hydrogens to the ligand.  Any suggestions to fix the problem?
 
Thanks,
