Doesn’t work as expected

Sounded good, looks good / well designed with simple options. However, the powerpoint slide viewer doesn’t actually work – when clicking the slide or left / right arrows the slide does not change. Furthermore, I wanted to restrict downloading the source file and although there is an option to prevent this, the native frame viewer has a download file option, which kind of defeats the point.
I suppose if you want a way to share documents in WP and are not concerned about copyright etc and downloading, then it does what it says on the tin.
