Need help

say I have this browser window open (there no scrollbar, address etc. on this window). I have an intro movie playind. At the end of the movie, a buttun will appear. Once clicked, it will get a new url. here is the code of that button:

on (release)
{
getURL(“http://www.gotospot.com/html/main.htm”, “_self”);
}

Here is the problem: if I were to use IE. After clicking my button, the window will have scrollbars; I really don’t want this. This doesn’t happen if I use Firefox or Safari. Is there anything I can modify on the code above to fix this problem?! Thank you so much.
