ok, there’s a new technote here that tells how to edit the CSS for the Flash help panel to change the font attributes.  It left out an old trick though.  If you’re using Windows XP and need to temporarily bump the font size of the Flash Help panel up or down you can click in the Help panel, hold down the control key, and use the scroll wheel on your mouse.  Note that it also changes the font size in Internet Explorer, but who uses that anyway? 

For a more permanent change go with editing the CSS like the technote says..  but for temporary things like doing a demo in a class or if you’ve left your glasses down stairs on the kitchen table, just control key and scroll wheel it.
