I know how to do this with html, but im trying to use fash catalyst program which doesn't let me edit the html. i found this video saying to go to file, html, change the window to transparent, then click publish & okay & your good to go! But, after I click publish i get a pop-up saying applications & installer settings & it asks for a code signing certificate!!??? im lost. help?
Open the html file in any text editing software (Motepad works). In the html web page there will hopefully be a "wmode" parameter specified in the embedding code for your Flash. Specify that to be "transparent".
