When a directory has subdirectories with mixed date/time date/year values in the last modified date column, the directories which have a date/time are accessible; the directories which have date/year begin with a space in the browser window and will fail when accessed. Here is the log window listing for a directory:

drwxrwxrwx   2 sigma    staff         12800 Feb 14 11:09 bsc

Double clicking on the browser window entry for servdir (which shows an initial space character in the browser window) gives this result in the log:

CWD /home/ servdir
550 /home/ servdir: A file or directory in the path name does not exist.

The 'mi' and 'users' directories can be accessed and do not show an initial space in the browser window.
