When the Internet Explorer closes

One of the only reason I'm using SmartFTP is the way it monitors my clipboard and pops up as soon as I copy an FTP's URL. I'm having a problem where when I've been doing that and I close Internet Explorer SmartFTP opens up three new windows and logs onto the last URL that I copied in each window. Is there anyway to keep it from doing this? Are there any other FTP programs that monitor the clipboard that way?
