Info Dir Problem with 21.4.12

I can display the Info directory (C-h i) and select an info file to view. I can then press 'd' to redisplay the directory. After the directory is redisplayed, if I wait a few seconds the info dir buffer is replaced with text-mode buffer displaying an editable view of the direcrory but with contents that have been munged. Any idea what's going on? -- Jake Colman Principia Partners LLC Phone: (201) 209-2467 Harborside Financial Center Fax: (201) 946-0320 902 Plaza Two E-mail: colman(a)ppllc.com Jersey City, NJ 07311 www.principiapartners.com
