While playing with multiple-choice menu's, it occurred to me that it
would be real nice if I could select several items at once by holding
the mouse button down and dragging it across several items.  I was able
to get this effect by issuing an UnGrabPointer request on LeaveNotify
events to a button.  After doing this I started getting enter/leave
notifications for each button as I dragged the mouse across my menu
items.

I'm trying to avoid messy interactions with the menu-item's parent.
While the above scheme works, it isn't very robust.  There's a
round-trip to the server for each button the mouse is swept over, so its
possible for buttons to be skipped by a fast user (or slow client/server) 

Is there a way to tell the server "don't automatically grab the pointer
when a button is pressed"?  (I've never understood all those options to
GrabPointer...)  Does X-Toolkit let you select multiple items with a
click-drag-release?  If so, what's the implementation strategy?
