Embedded Content problem

I have a problem with embedded content in blank modules.
i have embedded youtube videos as well as souncloud players into these modules, they're working perfectly and are looking fine in general.
but now (and only) Internet Explorer seems to have a problem with those, because site popups/dropdowns like arrow chat or jomsocial notification pop up behind the embedded stuff (but not behind the modul).
i've attached a screenshot to explain the issue better. do you know how to solve this? thank you very much in advance!

PS: i tried different module variations, but this doen't change anything.

Try adding wmode="Opaque" to your embed code.
such as below example

Code: Select all

<iframe title="YouTube video player" width="480" height="390" src="http://www.youtube.com/embed/lzQgAR_J1PI" frameborder="0">


Code: Select all

<iframe title="YouTube video player" width="480" height="390" src="http://www.youtube.com/embed/lzQgAR_J1PI?wmode=transparent" frameborder="0" wmode="Opaque">


See you around...
