Cannot move up or down folder level when connected via SFTP. (4253550)

Using Toad for Oracle 9.7.2.5 and 10 Utilities | FTP tool, I am able to connect to an SFTP site but is not able to navigate up or down sub-folder and files level.   This still works when connected to a FTP site. When connected to a SFTP site using Toad 8.6.0.38, I  am still  able to navigate up or down sub-folders and files by double-clicking on the folders. I could navigate back up by clicking on the up-arrow icon to the right of the remote system file path line. In Toad 9.7.2.5 the folder navigation on the remote SFTP site no longer works. You can't double click on any folder to go up or down one level. Re-specifying the folder path does nothing to help.
