Also, please can you refrain from calling it a "window" it's a modal. Windows, are new windows. I.e. a proper popup, not a modal. It's important you use the correct language otherwise you can create a lot of confusion.
Thanks for the recommendation. According to webdesign.tutsplus.com/articles/modal-and-modeles… the proper term for what I want is a want a "modeless box" (which is why I was trying to avoid calling it a modal)- apologies for any confusion.
