Property sheet will not open

[lawdy]

This is either a very strange question or a very simple fix. With a form in design view, I click on the DESIGN tab on the ribbon and then under TOOLS, I click on PROPERTY SHEET, whick opens on the form. Now I do that and nothing happens. It is the same with ADD EXISTING FIELDS. Neither one appears. Everything else seems to work ok.

Ok, I got it back. It was just hidden.
