Arrow keys in mainmenu are ignored always in my application.
I haven't found any case where arrow keys allow navigation in MainMenu.

I reported it in 

http://bugzilla.ximian.com/show_bug.cgi?id=79603

and in 

http://bugzilla.ximian.com/show_bug.cgi?id=79435

I found that those issues still exists in 1.2RC
