If you're developing applications with Adobe Flex, you'll need Flash Player 9 to view the applications. To get Flash Player 9 working in Flock, do the following:
Simply copy C:\Program Files\Mozilla Firefox\plugins\NPSWF32.dll to C:\Program Files\Flock\flock\plugins\NPSWF32.dll.
I've blogged about this on my blog. If you want to Digg it, do so here.
Hope this helps.
