click on the replay above on PokerStars, a new window appears where you can watch how the previous hand went and will open in a separate window
I think that he wants to detach whole information (chat/
hands/notes/stats/info) part of the window into separate window.
But if you want to replay hand history in visual mode as
@Gallarado777 says then yes, you should click one of "red squared" buttons. Then you will open hand replayer in separate window.
This one I want to separate it in a separate window from the table, the same as ggpoker and 888poker.

If you want to detach above mentioned information part of the window into separate window I'm afraid it's not possible. You can only hide it by clicking arrow on the right side of that information part.
