Writer not reflecting updates to document

Writer not reflecting updates to document

1. I uploaded a Word doc.
2. From the Documents tab I click on the "Open in Zoho Writer" icon
3. I made a small change to the document and clicked "SAVE"
4. Opened the Word doc and change is not reflected.

Am I doing something wrong?
I am using IE 7 with tabbed browsing. Also tried in Firefox

Thanks
Neil
