NT Personal 7.3 - Navigator acting up?

I'm having a hard time getting to grips with Oracle Navigator. I've created a load of tables both using the create table wizard, by hand, and directly by typing SQL statements in SQL*Plus. For some strange reason, just one of my tables refuses to be modified in Navigator. I can type changes and tell them to commit, but when I refresh the table the changes haven't been applied.

Can someone please offer some advice?

For reference, here's the description of a table that I *can* edit in Navigator:

SQL> describe DIALTEST

 Name                            Null?    Type
 ------------------------------- -------- ----
 COMMONKEY                       NOT NULL NUMBER(22)
 IAPNAME                         NOT NULL VARCHAR2(40)
 TIME                            NOT NULL DATE
 TESTBOX                         NOT NULL VARCHAR2(30)
 SUCCESS                         NOT NULL NUMBER(1)
 TOTALTIME                       NOT NULL NUMBER(10,4)
 CONNECTSPEED                    NOT NULL NUMBER(10)

And here's the one that I can't:

SQL> describe EVALQUEST
