transparent boxes

I want to make a new Flash window with a transparent background (still allowing you to see the stage background) pop up after I click on a button. Can anyone give me some advice and help? Thanks...

You can make the swf bg transp in html with the following:

1) go to file->publish settings->HTML
for "Window Mode" choose "Transparent Windowless"

this will add the correct param tag to the resulting HTML generated when you publish the movie (Shift-F12)

2) go to the html page in which you embedded the swf movie and add the following tag INSIDE the object tag:

<PARAM name="wmode" value="transparent">

Note: transparency only works with the IE browser, and does not work with Netscape....

Then just place a solid bg in the areas you want the bg to show.
