Gmail Adds 'View as Slideshow' Function

Gmail currently allows users to preview attached documents (.doc) and spreadsheets (.xls) in emails as HTML so that users do not have to download anything to open these files. Now you can even preview PowerPoint attachments by clicking on the 'View as slideshow' link below every .ppt attachments:
On click, you will be brought to a new window where you can preview slides by slides by clicking on the left / right arrows (A) or jump back and fro using the drop down list (B):However, like most ofsthe new features, it is pretty buggy. I have experienced a 'Conversion failed' error and was told that the 'document is unreadable and possibly corrupted'. And a few of my PowerPoint with Chinese characters are corrupted, showing boxes rather than characters. I suppose they will be fixed very soon. ;)
