Query Builder spinning

Thank you to everyone that has responded to this post.  That has resulted in finally getting a solution.  Here is what has our query builder now running:

run the following:

--------------------------------------------
declare
  lu_name_ VARCHAR2(30);
  pck_ VARCHAR2(2000);
begin
  FOR rec_ IN (SELECT lu_name lu_name FROM dictionary_sys_tab) LOOP
    BEGIN
      lu_name_ := rec_.lu_name;
      pck_ := Dictionary_SYS.Get_Base_Package(lu_name_);
    EXCEPTION
      WHEN OTHERS THEN
        Dbms_Output.Put_line(lu_name_);
    END;
  END LOOP;
end;
-----------------------------------

If you get data back you have to change the LU name in the view in the comment section for all invalid lu names, 

i.e. FROM:

COMMENT ON TABLE AGRX1APP.AGR_RESOURCE_EMP_LOAD_CAPACITY IS 'LU=AGR_RESOURCE_EMP_LOAD_CAPACITY^PROMPT=AGR_RESOURCE_EMP_LOAD_CAPACITY^MODULE=CUSOBJ^';

TO:

COMMENT ON TABLE AGRX1APP.AGR_RESOURCE_EMP_LOAD_CAPACITY IS 'LU=AgrResrceEmpLoadCapacity^PROMPT=Agr Resrce Emp Load Capacity^MODULE=CUSOBJ^';

 
If you do not get anything, execute the following script 

-----------------------------
BEGIN

    Dictionary_SYS.Rebuild_Dictionary_Storage_(0,'FULL'); COMMIT;

END;
----------------------------

Then refresh all the caches in refresh server caches in IFS.
