Hi,
This is an inherent problem with Flash objects. For whatever reason, Adobe decided that they would ignore the built in z-index system of browsers and set their own objects to the top at all times. Here are instructions on how to get the Flash objects to behave correctly:
You need to add this between your OBJECT tags:
[code:2p1rm53u]<param name="wmode" value="transparent">[/code:2p1rm53u]
And this in an EMBED tag
[code:2p1rm53u]wmode="transparent"[/code:2p1rm53u]
So your code should look something like this:
[code:2p1rm53u]
<object>
<param value="blabla.swf" / >
<param name="wmode" value="transparent" / >
<embed src="transparency.swf" wmode="transparent" type="application/x-shockwave-flash">
</embed>
</object>[/code:2p1rm53u]
