File Manager not working properly

File Manager not working properly

The file manager for Zoho Sites is garbage. See the attached image.

- If I click on "New Folder" and type in a name, no folder is created.
- If I select a file and click "Trash", the web page freezes on "Please Wait..." forever.
- If I select a file and click "Move", nothing happens at all!

The only button that does work is "Upload from computer", but that falls well short of the mark. How do I fix the File Manager?
