To move any widget into its own foating browser window, go to the widget task menu (...) and use the menu item "Move to child window".
The result will be that a new page is created in the left bar with that widget on it, it will have the new window icon next to it. (This will be helpful if the floating window gets hidden behind other windows you have open. Click on this page and it will bring the floating window into view.)
And, you'll see the widget open in it's own browser frame.
If you close the floating window or log off, next time you log on you can access the window out of page from the left bar. And reopen it as a floating window from the page task menu (...).
