Quick Flash! Why isn't this scaling to 'showall'?

<script language="Javascript" type="text/javascript">
AC_FL_RunContent(
'codebase', 'http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=10,0,0,0',

'loop', 'true',
'scale', 'showall',

'allowFullScreen', 'false',
'allowScriptAccess','sameDomain',
'movie', 'semi14new',
'salign', ''
); //end AC code
</script>

Movie is requiring ShowAll to be Manually activated (right-click)....
Please, why?
Help very much appreciated.

there were two Actionscript instances 'overwriting' ShowAll.
