[PyMOL] incorrect bonding

[bsanders]

Hello,
When I read my .pdb into pymol, for some protein ligands, the program adds a
bond between two atoms that doesn't exist.  I believe that the distances
between these atoms must be under the default cut-off that pymol uses to define
a bond.  Is there a way I can change this defaut number?  Is there an easy way
to get rid of this extra erroneous bond?  Any help or suggests would be greatly
appreciated.
Thanks!
