Seems like this should be simple enough. Click the browse key, locate this mystery file, and assign it. Evidently this a national security issue as I can't find a clue. I could just use the F5 key but I'm a touch typist, it's rather dark where I work and I can't just hit the key like I would qwerty keys, nor can I see it without locating a light and getting it on the keyboard. I do have these huge programmable buttons. When I try to reassign them in Microsoft Mouse and Keyboard Center, it offers the browse button to assign a program. I've searched System, System32, syswow64. Nothing suggests it does 'refresh'. I'm thinking now it must be something like a run dll type thing. Any help is appreciated
