Security/Javascript problems

I have a piece of javascript I wish to call from a swf. I am simply using

[AS]
getURL( “javascript:funcName();” );
[/AS]

This works fine in Mozilla browsers, and all others I’ve tested, but surprise surprise, IE completely fails to call the script.

I have allowScriptAccess set to always.

I have also used Adobe’s command-line LocalContentUpdater tool to ensure the swf has network privileges.

IE still refuses to do anything.

Has anyone got any ideas on this, I’ve been searching for several hours, and everytime I think I’ve found the solution, IE just laughs in my face.
