Dear RDKitters,

when testing the PyMOL integration (given the iPython notebook from the 
tutorial):

"
from rdkit import Chem
from rdkit.Chem import AllChem
from rdkit import RDConfig
import os
from rdkit.Chem.Draw import IPythonConsole
from rdkit.Chem import Draw
cdk2mols = [x for x in Chem.SDMolSupplier('data/cdk2.sdf',removeHs=True) 
if x is not None]
from rdkit.Chem import PyMol
v = PyMol.MolViewer()
v.ShowMol(cdk2mols[0])
v.GetPNG(h=300)
"

I run into an error:
"
----> 2 v.GetPNG(h=300)

C:\RDKit_2013_03_1\rdkit\Chem\PyMol.py in GetPNG(self, h, w)
    214       except IOError:
    215         time.sleep(0.1)
--> 216     os.unlink(fd.name)
    217     fd=None
    218     if h is not None or w is not None:

WindowsError: [Error 32]"

The actual error message is in German: there is already a temporary PNG 
written, that cannot be over-written.


Cheers & Thanks,
Paul
