Recommendation -
When you post a Youtube video near the top of a thread (I'm using the legacy postbit too) and subsequently try to use the Thread Tools drop down to edit/stick/whatever, the menu drops down behind the YouTube layer.
One of my admins suggested the following alteration:
Code:
<object width="425" height="350"><param name="wmode" value="transparent"></param><param name="movie" value="http://www.youtube.com/v/{param}"></param><embed wmode="transparent" src="http://www.youtube.com/v/{param}" type="application/x-shockwave-flash" width="425" height="350"></embed></object>
