Fonts in Flex 2
While working on a transition recently in Flex 2 I had some issues with button text not fading along with the rest of the components. Digging into the documentation I ran across this nugget of information:
The Dissolve, Fade, and Rotate effects only work with text rendered using an embedded font. If you apply these effects to a control that uses a system font, nothing happens to the text.
Maybe this is just known but it was a surprise to me. There are other helpful font tidbits on the Using embedded fonts with effects page.
