I'm using Windows 7, Microsoft Office 2016.
Today, suddenly, right-clicking on the title bar of an Access form did not produce a shortcut menu.
Right-clicking on a form detail does produce a shortcut menu but right-clicking on the title bar does not.
I installed a fresh Office 2016 from my Microsoft Account where I purchased it. Same problem.
I did not install any new software today.
I created a new blank database: same issue.
I opened an old database not accessed in months: same issue.
I copied a database and opened it on another PC and NO ISSUE.
I went to File>Options>Current Database>Ribbon and Toolbar Options and "Allow Default Shortcut Menus" is checked.
