Ok, if i try and view the above site with flashplayer 7 installed on either windows or mac, and click the "all chemicals", "All locations" or any of the other buttons across the bottom of the screen the text in the window on the right hand side doesn't display. If I disable the embedded fonts in my actionscript they display. If I install flash player 8, they display. All of my swf's for this site have been exported as flash player 6.0 and actionscript 1.0.
This is really frustrating, I haven't been able to find any similar problems anywhere.
