This release changes the label in the Config window to "Your Callsign". Both a development release and a full release are available via http://www.dxlabsuite.com/download.htm By default, both self-extracting executables target c:\program files\pathfinder rather than c:\program files\pathfinder4 so if you've been using c:\program files\pathfinder4, you'll need to modify the pathname before clicking the self-extractor's UnZip button. This inconvenience will be short-lived; in the forthcoming Launcher, once you specify a DXLab application's folder you can subsequently upgrade it with a single mouse click. If you already have Pathfinder installed, the Configuration window's ambiguous callsign label most likely no longer troubles you. Thus I suggest that you pass on the 4.3.9 development release -- at least until the new Launcher arrives. 73, Dave, AA6YQ
