you can target a window when hyperlinking from flash by clicking on the getUrl() function (i am assuming you know how to do that) and in the three text boxes that follow you should see a box with Window next to it and a drop down arrow on the extreme right. Click on it to target where your link should open. You can even define your own target as is used when targeting flash with frames by typing in the name of the frame you wish to target the link in.
