Hi,
I'm unable to use main menu if I use TAdvMetroForm instead TForm. There is no way to click on menu or choose menu item unless form is maximized.
Recommanded solution:
Put a TAdvDockPanel on this form with a TAdvToolBar with setting FullSize = true on this TAdvDockPanel. Then connect a TAdvMainMenu to this TAdvToolBar. This will result in a correct menu for a TAdvMetroForm.
