For 2.6 dialogs, you can make the Accept function ignore events for
targets that are outside the dialog's interactor hierarchy.  See
BasicDialog::{Forward,IsAChild} in src/lib/Unidraw/dialogs.c for an
example.  For 3.1 dialogs, the default implementation for the run
function does a grab, so there should be no problem.
