Popup tutorial problems

hey all, i used the code from Kirupa’s centered pop-up tutorial for MX and it works wonderfully in Safari and Firefox. The problem is in IE it won’t spawn a window at all, nothing happens. Now I know Kirupa’s does, so I’m very confused as to why this is happening. I am working on a Mac using Flash 2004. I’m desperate to solve this problem if anyone can tell me what is going on or point me to code that will work in IE I would appriciate it.
