Flash gotcha down? Spending hours wondering why Microphone.get() doesn’t produce a dialog box?

Here’s a choice piece of information in the Microphone section of the Flash Media Server client guide:

Flash Player displays a Privacy dialog box that lets the user choose whether to allow or deny access to the microphone. Make sure your Stage size is at least 215 x 138 pixels; this is the minimum size Flash requires to display the dialog box.

What it fails to mention is that if Flash doesn’t display the dialog box, it won’t record audio. I did RTFM when it came to the developer’s guide, but this tidbit is hidden in the client reference. I usually don’t read references front-to-back, but maybe I should.
