x11-toolkits/open-motif*: EditRes functionality is unreliable on 64 bit

Like x11-toolkits/libXmu, the same problem exists in Motif and
editres(1) will not pop up the resource box,
displaying, "this widget no longer exists in the client."

Additional discussion and patch posted near the end of the
discussion at,
