flex4: swfloader doesn't properly load games

I have several flash games that when i load them in my firefox browser they load fine开发者_Python百科, but when i load them with swfloader using flex 4 (flash builder) they load until 100% and don't show the start menu.

any ideas how to resolve the issue ?

the loaded flash and the website that contains the page with the loaded flash where not on the same applicationdomain, besides fixing that.

i added the parameter SWFLoader.loadForCompatibility=true

 *  This flag is ignored if the content must be loaded into a different

 *  If <code>true</code>, the content loads into a sibling ApplicationDomain. 
 *  If <code>false</code>, the content loaded into a child ApplicationDomain */
