Hi All, I think I may have found a bug in the above program in the fact if you press F1 - HELP KEY it comes back and says "HELP IS NOT AVAILABLE NAU.HLP MUST BE IN THE DEFAULT DIRECTORY" I have NA.EXE, NAU.EXE, NAQSL, NAU.HLP all in the directory c:\NA and I see that as the default directory, or do I have it wrong?
