rgb correct title are radiobuttgroup change item generate lost focus event 🙂 another thing, in this example when messagebox appear in about window can see avalonia about ? see screenshoot lostcontrol.objo2kB
Garry I’ve reproduced both problems with your project and logged them separately: RadioButtonGroup fires focus events when moving between options. Moving between options incorrectly fires FocusLost for the whole group, which triggers your message box. That event should fire only when focus leaves the group. MessageBox exposes About Avalonia in the macOS application menu. While the message box is open, the application’s menu switches to Avalonia’s default menu. That makes “About Avalonia” available and explains the window in your screenshot. The normal menu returns after dismissing the message box. The menu problem also occurs with a separately opened message box, so it needs its own fix. Thanks for the example; it helped confirm both bugs.
