HOW TO DISABLE "..press spacebar to activate this button" that appears on my swf file

Hi… i don’t know which category should i post this, but since im using mx2004 I just posted it here.

Why do my swf files need to be activated by clicking with a mouse or spacebar while i see other pages like yahoo no longer requiring the user to do it?

Please tell me… i know this may seem simple to others but I don’t have any idea how to fix it.

Thanks

BUDDY
