Writely isn’t working fine in IE or Firefox. At least the menu which appeares on clicking the side arrow appearing alongwith every document isn’t appearing on clicking the down arrow. Therefore there isn’t any option for modifying the document properties. If you open All Documents or any other scren than Active Documents and then click on down arrow, strangely, it jumps back to the Active Documents screen.
In order to open the document, you need to click on the document name and it opens up in new pop-up window. In this window, you can edit or modify the document properties and on clicking done, it closes down and comes back to the previous screen. If you close the previous screen, on clicking Done button, it loads Active Documents in open window.
