I haven't really looked at the XROI code, but I suspect
it will have to be modified so that in the section dealing
with MOTION events associated with drawing the rubberband
box you are also looking to see if the viewport needs to
be moved. No time this morning to check to see if this
is easy or extremely hard. XROI has never really been my
favorite example of well-written IDL code. :-)

Cheers,

David
