Hi Oliver,

With performClickWithFrame: inView:, the menu will pop up as if a 
popup button were positioned within the frame parameter, interpreted 
as a rect within the bounds coordinate space of the given view.  To 
pop up a menu where the user clicked, pass a 1x1 rect whose origin is 
the location of the event within the bounds of your view, as the 
frame parameter.

I hope that's clear,
-Peter
