In Access 2003 and earlier if I want to show hidden objects I would use the tools Menu item and then Options and select the View tab. Then I check the check box and all hidden objects are visible.
How do I do it in Access 2007?
On the navigation bar on the left hand side of the screen, near the top of it. There is a "<<" control. Click it to show a drop down menu. The option should be in there!
Right-click on the navigation pane title bar and select NAVIGATION OPTIONS and then you will have the options for displaying hidden or system objects in the bottom left of the dialog that pops up.
