I created a simple app with a MainForm and mdi child forms, attaching an UltraTabbedMdiManager with the MainForm.

I want to handle some special key combinations on both MainForm and child forms, e.g., Ctrl+ F12.
So i created event handlers for KeyUp events in both MainForm and child form classes.

However, it does not seem to work: when i press keys, it would not go into any of the event handlers.

Have you got any idea what's going wrong? any solutions for this?

Thanks!
