Correct. If no connectivity information is presented then Jmol will
calculate connectivity.

You are correct. The rule is that if connectivity information is present
in the file then Jmol will respect that connectivity and will not add any
more bonds.

(Note that PDB files are an exception to this rule, because the PDB
specification calls for optional CONECT records that specify connectivity
in addition to the 'normal' bonds.)

Regarding your issue Francois ... I have been doing some work to allow
people to use scripting commands to add and delete specific bonds. This
functionality will allow you to explicitly select the *incorrect* bond and
delete it.

I plan to release this code within a week.

So you may want to test this new functionality before you go to the
trouble of adding connectivity to your CML files.
