I hid this table previously, then went to Navigation options to add the check back beside the table, but it won't show... I checked the whole list in case it popped up in another group, so then I went back to navigation options to show hidden objects, and there it is, but still grayed out.... so I kept trying a few different sequences of checking and un-checking to see if I could kick start it back, but no luck... whats up with this?
