i think it should be a new popup window, thats if u dont want any address or tool or status bars. i have used the one on kirupa site and it works great to me, try it:
on (release) {
//customize the window that gets opened
// 0 equals NO.
// 1 equals YES.
address = “pics/p0.html”;
target_winName = “kirupa”;
width = 300;
height = 263;
toolbar = 0;
location = 0;
directories = 0;
status = 0;
menubar = 0;
scrollbars = 0;
resizable = 0;
//sends data back to the function
openWinCentre(address, target_winName, width, height, toolbar, location, directories, status, menubar, scrollbars, resizable);
}
