Transparacy problem on illustrator export?! plz help

hi there, i have knocked up some fairly simple buttons in illustrator, they use transparacy… i have exported them as .swf files and loaded into flash but the transparacy messes up all the time…

see example (buttons.gif) the top line is how the should look and the bottom is how flash treats the transparacy layers…

is there any way i can get these into flash (in true vectors) and maintain the transparacy??

Many Thanks,

Ben
