I have use screen in a mac terminal for a long time and all has worked as desired.
Recently when setup the "chdir" in screenrc doesn't change to the indicated directory before creating the named screen in screenrc. The screens were created but all are in my home directory. I can cd to the path of the "chdir" manually and all else works properly. The c-a command plus its number reports the correct screen name. Any ideas? Thanks. -- XB
