Power Point Slide doesn't work with Chrome

Hello,

Steps to reproduce it:
Access a page in Confluence where has a powerpoint slide.

Expected behavior:
Powerpoint should slide page by page.

Actual behavior:
That does not work properly with Chrome Version 19.0.1084.46. Even with we download "Docs PDF/PowerPoint Viewer (by Google)" extension to the browser.

Version:
This is on Confluence 4.2.2

It used to work with the same browser using MAC.

P.s:
Works with all browser using Ubuntu/Linux.
Safari works fine; Firefox works fine.

Please, advise.
