When working with the Preferences dialog one can manipulate all aspects of the
listed columns, eg. Title, Type, Fields, etc.

The Fields and Field Occurrence entries have only relevance to the Custom
column type. Any click in these entries makes the Type automatically change
from its original to Custom. Thus, even inadvertently clicking these entries
changes the column type, whereby the only recovery option is to Cancel the
whole dialog and start over again having to redo all the work. Running the risk
of not even noticing this automatic change, the user may not even be aware of
this change until an empty column in the packet list appears.

I would recommend to make the Fields and Field Occurrence entries inaccessible
unless the user explicitly selects the Type to be Custom first. 

If this is deemed undesirable, then the dialog should not be allowed to be
closed unless an actual Fields _expression_ was entered for every Custom type
column. This at least would alert the user of something configured incorrectly
if a change was made inadvertently.
