Can't delete access objects from All Access Objects

[TerraEarth]

I am modifying a colleague's access file but for some reason I cannot delete anything (tables, forms, reports, etc.) from the ALL Access Objects window located on the left hand side when you open the file. Any idea why this might be the case? I've looked around and tried a few things but nothing seemed to work.

On all my other files I can delete objects just fine, it is only on this particular one from a colleague which I'm having issues with.

Is the file an accde ? This is an executable and design cannot be modified.

ACCDB actually, I'm able to import new objects into the file but I can't delete objects already in the file.

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

Sounds like the navigation pane is locked. This results in certain context menu items such as rename and delete being disabled

If that's the case, open the VBE and in the Immediate window type

DoCmd.LockNavigationPane False

That should restore it to normal

Still no luck unfortunately.

I inherited this file from another user (long gone) in another department and there's no log or anything of that sort that explains what might have occurred to make this happen.

Can you show a screenshot of the nav pane and/or upload your database.
There is a chance that you have corruption. You should try each of these in turn - compacting, decompiling, copying all objects into a new blank database
