but the app was losing focus for a very good reason - the wm was obeying its
focus policy. the way menus were done was such that displaying the menu would
validly trigger the focus policy - and the wm has no way of knowing otherwise if
it should really remove the focus or not because it has no idea what this new
override redirect window is - just that the client app window got a leave event
and not due to a grab etc.

not theory - i was wathcing the events from the wm's side and was using xmon
logs too. i was working with my wm and ooo - i knwo what was happening.
enlightenment gor a mouse out from the app window (as it entered the menu
window) BUT the mouse leave DETAILS and MODE did not indicate a grab - they
simply indicated the same kind of mouse out you would get with the window
entering any other widnow on screen that may become overlayed above the client
the mouse was over (a new window, etc.). e went "ooh mouse out" obeying strict
pointer focus and thus ooo lost the focus - closing its menu. at this point the
menu window was closed - e got the mouse in again for the app and slapped focus
back onto ooo. the fact is the events do not help you differentiate if this
window was a menu window for the app or some other override redirect window some
other program put up (some splash screen or something that isnt managed). :)
