If you place a screener where there is a Flash object, the Flash object will display before the screener, essentially blocking the screener from view. We'd recommend trying to place screeners away from Flash objects if possible. But if there's no other way, try adding this "wmode" parameter set to your flash code (i.e. between your <object> </object> tags):
<param name="wmode" value="opaque" />
AC_FL_RunContent('codebase', ... 'main' );
Add those same parameters as above, so it looks like this -
AC_FL_RunContent('codebase', ... 'main','wmode','opaque');
This isn't a guaranteed fix, but it may work. If it doesn't, unfortunately, there isn't really anything we can do on our end - good ol' Flash.
