I am using MS Access 2003 (project - .adp file) with SQL Server 2000 backend.
I have a form that has several individual checkboxes.  (These checkboxes are
NOT part of an Option Group).

When you create a new record and go to a certain drop down list field in the
form and make a selection, the result is that all the checkboxes on the form
become checked.  I have looked for a VBA driven event that might be
responsible, but have not found any events to explain this.

Also, when you are in an existing record that has several of the yes/no
boxes checked and you want to de-select several boxes, the form will only let
you de-select 1 yes/no box and will not let you de-select the other yes/no
boxes.  Again, I have not been able to find any event driven VBA to explain
this behavior.

I am looking for ideas of where else to look.  

Thank you,
