MS Access Navigation Pane disables buttons

[SunnyD204]

I've created a database in MS Access 2007.


There are buttons I use to close one form and open another.
I use this method to traverse through several forms.

I notice that when I have my Object Explorer (Tables, Forms, Reports, Query Listing) closed or minimized some of my navigation buttons (used to close current form and open next) are unrecognizable by Access.
I can't click them at all.
However, when I expand the Object Explorer they work and are clickable.

What am I missing? Is there an option that I don't have set correctly for the button to work in either

Thanks

Never encountered that. If you want to provide db for analysis, follow instructions at bottom of my post.
