title: Font rendering in flex sometimes results in characters a couple pixels lower
body: <p>Sometimes while typing in a textarea in Flex many characters will be rendered at one height then at some point on that same text line the rest of the characters are rendered a couple pixels lower than the rest.  Here is an example, look at the last 'I' character, its low:<a href="http://img.skitch.com/20091031-ej5n28akygnm3gmxcjx731ic85.jpg" rel="nofollow noreferrer">alt text http://img.skitch.com/20091031-ej5n28akygnm3gmxcjx731ic85.jpg</a></p>
  
  <p>Sometimes changing the font size will fix this but its not consistent and its not something I can detect (and fix even if I could).  Anybody got an idea why this happens?  It happens for embedded and non-embedded fonts.</p>
  
  <p>Thanks,
  Sam</p>
