Glad it worked! 🙂 I've found that, whatever corrupts the help viewer prefs files or cache, I'm having the problem more and more frequently. Guess it means that one of my programs that I run help on is a bad, bad, bad 🙄 Although, I mostly use help viewer for the MacOSX help. Hmmm... 😱
But my issues mostly seemed to be solved by deleting the three prefs files and the one cache file, a trick I learned very recently right here on MacRumors. 😉
