True, But this is being very unfriendly to the window manager, and basically
saying that it should completly ignore this window.  While this may be okay 
for popup menus, it is not always the right thing to do when you want to place
a window on the screen at a given location.  Please don't use override
redirect unless you are putting up a very tempory window.  I good rule of
thumb is don't do a override redirect unless you are also doing a pointer
grab.

No you are not missing anything, But you can use XtTranslateCoords() to 
find the actual location.

Possible that either your window manager or application (Xt??) is confused,
but without more info it is hard to say.
