Reset configuration

Quit Bridge if Open. Just before clicking on Bridge in the Dock or double-clicking the application for the Mac, press Command-Option-Shift. For PCs, press Control-Alt-Shift. Then open Bridge, BUT KEEP your fingers on those keys until you see a window pop up. From the window, the options are: “Reset Preferences" and "Purge All Local Cache Files.” Pick the first one (unless you want to also purge your cache files, never a bad thing, really).
