Need help with Browser Window

My browser window keeps popping up automatically. I created a flash button and added "javascript:Launch(my URL) in actions getURL.

In Dreamweaver I added the following script in HTML in between the <body> tags:

<SCRIPT LANGUAGE=“JavaScript”>
<!-- Begin
function Launch(page) {
OpenWin = this.open(page, “Alfa”, “toolbar=no,menubar=no,location=no,scrollbars=no,resizable=yes,width=400,height=400”);
}
// End -->
</SCRIPT>

The button works fine, but now everytime I load the page, the pop-up window comes up by itself. In Flash, I tried with and without a URL target, but I get the same results. Any suggestions??
