Ah, thanks for the clarification.  I was already using gtk_grab_add().  If
grab_add applies to already-received-but-not-yet-processed events, then I
guess I need to look elsewhere to find the source of my problems (that
occasionally, the button_release event doesn't seem to be received by the
notebook, so the pointer stays grabbed until the user clicks again). :)
