When I am working with Sources I sometimes need to see the entire line of a Source. Individual names appear at the end of Sources and many times that is exactly the info I need to see. I have discovered that if you move the entire FTM window by grabbing the title bar at the top and moving it to the left that I can then select the side of the screen and drag it out to the right thereby exposing the entire row of Source information. This is especially helpful when Replacing Sources because that screen opens in a collapsed view and makes it very difficult to find the record you are looking for.
