I create two tables in the table designer fine. Google results tell me when I 'OPEN TABLE DEFINITION' by right clicking a table a 'TABLE DESIGNER' menu should appear in my main menu, where I can click 'RELATIONSHIPS' to create the relationship. This menu does not appear... I played with the Menu under 'TOOLS->Customize...' and moved TABLE DESIGNER up the list. Now it does appear in the menu (but all the time)... however it is greyed out all the time.
Very frustrating, this seems to be a bug.. maybe express only bug?
