Sounds like the MIT Lisp Machine (and, by inheritance, Symbolics) pop-up
menu mechanism (pop-up confirmations are simply menus with only one
choice).  One difference is that there is an option (which I think is on by
default) to pop-up the menu at a location that puts the default choice
under the mouse cursor; the cursor only has to be warped if it is close
enough to the edge of the screen that part of the menu would be off the
screen (the LispM window system doesn't support off-screen windows).

In general, I've noticed that X Windows has adopted hardly anything from
the LispM window system.  Is this some kind of YIH (Yes Invented Here)
syndrome?  Next to the Macintosh, the LispM window system is probably the
nicest window system around, and Symbolics's enhancements to it in the last
few years are phenomenal.  Yes, it still has some annoying limitations
(windows must fit on the screen, the active window must be on top,
updates to partially-obscured windows aren't usually visible until the
window is raised), but many of the UIMS features are great (an automatic
mouse documentation line, extensive support for mouse-sensitive regions,
very good management of keyboard focus).
