Closing box

Followed step here: https://www.ads-software.com/support/topic/whats-the-link-to-close-the-window

However, while the box closes, it also causes the window to reload and the box displays again.

Could you give me a link that makes this button work in the same was as the cross to close the box (STB.close is the class-id for the cross).

Thanks!
