I know this is little consolation, but my users with FileZilla had to switch to ws-Ftp due to the permission problem you mention.
Once they did switch they were able to change permissions successfully.
This was not a server or WAMP problem.
(There seems to be an access bug in FileZilla)
Hope this helps,
Paul
