I’m trying to create the centered pop-up window. i want my window to contain some basic info about a band. i have completed the tutorial, but when i do it, it opens up the pop-up window, but it also opens up my browser with this listed in the address bar:
javascript:window.open(‘[http://www.jpmediavisions.com](http://www.jpmediavisions.com)’,‘band’,‘width=400,height=300,toolbar=0,location=0,directories=0,status=0,menubar=0,scrollbars=1,resizable=1,top=’+((screen.height/2)-(150))+’,left=’+((screen.width/2)-(200))+’’);void(0);
what is this and how do i get it to just open up in the pop-up. also, when inside actions, does the address have to be a url? i haven’t created the url yet, do i have to do that first before i can do this?
thanks for all your help.

maybe the problem is that you are testing your swf inside flash.
the pop-ups in flash only work properly when the movie is loaded in a html page.
press F12 to make a html-preview in flash
