Hi cavsix
What the database server you use and is your odbc driver updated till last version ??
based on my experience (i use CR XI, Mysql5, mysql odbc5), it is also related to the option you have made in your connection (dsn).
For example, when i choose to display tables and views (option inside data explorer box), the DSN will show the "Add Command" menu and the list of all tables and views. But when i choose to display tables, views and stored procedures, the DSN will only show the "Add Command" menu and the list of all stored procedures. It doesn't show the list of table/view anymore
