startSlide problem with embed code

[TCavalie]

Hello everyone,

"startSlide" parameter seems not to work with embed code. When I take
the embed code generated from the slide share website, it works
perfectly with the old one (flash) but it does not with the new one
(iframe).
Examples :
http://www.slideshare.net/slideshow/embed_code/12204447?startSlide=13
and
http://www.slideshare.net/slideshow/embed_code/11382127?startSlide=11

Any idea ? Do I do something wrong ? Thank you take the time to answer
me, great job by the way.
TC
