Hand cursor issue

[FONT=Times New Roman][SIZE=3]I have made a Flash banner and needed it to be always clickable (a link to popup page) throughout its playtime. So I created a button (size of the banner, on the bottom layer) and assigned to it the following action:[/SIZE][/FONT]

[FONT=Verdana]on (release) {[/FONT]
[FONT=Verdana]getURL (“javascript:NewWindow=window.open(‘ad.html’,‘newWin’,‘width=320,height=240,left=300,top=300,’);NewWindow.focus();void(0);”);[/FONT]
[FONT=Verdana]}[/FONT]

[FONT=Times New Roman][SIZE=3]It works, but when cursor moves over the banner it does not change to hand cursor that indicates a link. How can I make it possible, make hand cursor appear? I’m not too well versed in flash code, so please be patient with me. I use Flash MX v.7.2 Please help, as I have already spent a whole day in serach and experimenting with no results.[/SIZE][/FONT]
