I am using pymol 1.3 and having trouble with doing manual superposition with my structures. I am able to download my structures, select the portion I want to move manually and, after deprotecting it using the action menu move it using the shift-mouse editing command. When I do this with my selection shown in cartoon mode, things look great, but then when i switch to show my selected residues as  sticks,  the sticks become huge --they  get bigger  and/or  smaller as I move the structure.  Ideas on what I may be doing wrong? Hope this makes sense. Thanks, Suzanne
