We note some difficulties with their analysis and present two novel backgrounds of string theory with 1+1 noncompact dimensions that satisfy their conditions yet possess 16 or 24 supersymmetries. It is difficult to believe that such backgrounds could be unstable.9 pages, no figures. LaTeX2e (using utarticle.cls and utphys.bst)High Energy Physics - Theorytext
