[cvsnt] unable to remove directory structure

[Mike Kinsey]

Using WinCVS 1.3.13.1 and CVSNT.
I'm unable to remove a directory structure from the repository. My 
working directory is empty and the file that was in the repository in 
that directory has been removed. I've got prune directories turned on.. 
When I try to update the directory of the parent of the one I want to 
remove- in the log window it displays the deleted file as having been 
removed, but it does not remove the directory.

What am I missing?
