I am testing some swf onLine and I see a huge difference btwin CRT screen and TST screen. The alphas are totally wrong on the CRT (70% or 20% on a TFT screen) they are close to 0% on the CRT screen.  
( I built the site with a TFT screened PC…)  
What a disappointment. Is that normal, did I miss sthing ? what can I do ?
