Unable to delete remote directory

Using Version 5.5.3 with Windows XP and Unix Server. Using FTP. Can remove files, but this is the first time I tried to delete a remote directory. Tried delete key, F8, File - Delete (grayed out) while the empty directory is highlighted. Am I doing something wrong or missing something obvious. Help mush appreciated.

Deleting directories is the same as deleting files. Maybe you have selected the directory on directory tree instead of file panel?

Ah - doubleclicked on the empty directory - that did it.
Knew it had to be something I was not seeing.

Thanks.
