Projects, new document wont save

Zoho's product management software is great but I am having a problem with making new documents under the documents tab.

When click on new document a new tab opens with a writer module, I can download as, I can view the print preview, the only problem is that the save button does not work.

I tried ie and firefox, saving a new spreadsheet works fine, uploading and viewing documents works fine. It's just saving a new document in projects that seems to be giving a problem.

Am I the only one with this problem or is it just a bug that has to be fixed?

Any chance you can help me out with this?
