Flash Player 10 and Content Disposition problems

Well, Adobe have done it again. Their latest update of the Flash Player messes up a lot of sites by simply not loading the flash movies.

Starting with version 10,0,2, if Flash Player sees a "Content-Disposition: attachment" header while downloading a SWF file, it will ignore the SWF file rather than play it.

...

This change will affect any SWF file whose HTTP server specifies "Content-Disposition: attachment" while serving the SWF file. This change affects SWF files of all versions played in Flash Player 10,0,2 and later.

This is affecting me. I am using the wimply player and use swfobjects (the wimpy version) to embed the flash into the site. Works fine on Flash player 9, but not on 10.

I have tried the following in my htaccess file:

<FilesMatch "\.(swf|mp3|xlm|jpg)$">
Header set Content-Disposition inline
</FilesMatch>

But no luck.

Can anyone please help me how to overcome this irritating issue? How do I set the header to inline, or switch it off all together?
