[PyMOL] problem with "distance"

[vincent C. <vin...@ib...>]

Hi,
I've just purchased v1.6 and installed it under MacOS 10.6.8.
I have a problem with using "distance" from a script, as well as via the 
wizard.

my pdb has 12 chains.
when I type: distance d1, molA and chain a and resi 53 and name o, molA 
and chain d and resi 8 and name n
the distance is drawn between: chain M and resi 7 and atom cg, and chain 
I and resi 53 and atom o.

I don't understand the error. So I turned to the wizard ->measurement. I 
click on the atoms that are in front of me, and the distance is drawn 
again between  chain M and resi 7 and atom cg, and chain I and resi 53 
and atom o.
For a proof, I'm pasting the top screen where the names of the atoms I 
clicked is:
You clicked /molA//A/SER`53/O
Selector: selection "sele" defined with 1 atoms.
You clicked /molA//D/GLY`8/N)

I was previously under 1.3 and didn't have this problem.
Can you help me?
Vincent
