Hmm, this has got to be something simple, but I can’t figure it out.
This db has several continuous forms, but none of them have the option of right-clicking to filter by selection (or any of the other right-click options). If I open the db using the Shift key, and then open the forms in form view, the right-click options work, but if I don’t open it with the Shift key, the options don’t even appear when right clicking. The form properties are set to allow filters.
Ooops: Startup > Allow Full Menus was unchecked
