When you are opening many espaces to update references, sometimes when it is doing a lot you get popup windows asking if you want to refresh references. With many windows open, they tend to show up behind other windows. It is difficult to find the popup window. When the popup window is open, it prevents you from doing anything in any of the other open windows. It will be much more efficient to move this validation as an error/warning to the True Change window. Allow us to right click on the entry to "refresh references".
