const WM_INITMENU = 0x0116;
win.hookWindowMessage(WM_INITMENU, () => {
    win.setEnabled(false);
    win.setEnabled(true);
});

I think a proper solution to this should still be provided.

The “system-context-menu” event is never triggered for me under Electron 11.0.3 and Windows 10, I’m using frame: false.

“system-context-menu” is still broken for me under Electron v12, it’s just not triggered.

Using Electron 16.0.4. This issue still persists. With frame: false the system-context-menu event is not triggered.

Thank you for your help, I have completed the effect I want, thank you!

@yangsen9608, you’re supposed to add the custom menu popup code inside the event handler, after the win.setEnabled(true); line. This works for me on the latest Electron version.
