When applying a blend mode to a movie clip and graphic within the .fla everything is fine. Play it in Flash player 10 and the blend is not applied. Play it in Flash player 9, all is okay. Any ideas?

I have had to uninstall player 10 and reinstall player 9 plugin for browsers.
All working again, but I am very concerned to to the use of player 10 playing
any swf that has not been developed in flash cs4. Are all flash files now going
to have to be rebuilt to work within player 10? Will only take me about 5
years. Great!

I know its not a public release so fingers crossed everything will be fixed
when it goes live.

Anyone have any answers?
