FWIW, I haven't researched it all yet, but on my NT 4.0 I can't open the help
files--tells me I have an old version of help. So, I read 'em on my 95 machine. I'm
sure it's solvable--just don't have any extra brain cells for this problem right now .

If my half dead brain cell recalls correctly you will find two versions of help in WinNT, "winhlp.exe" and "winhlp32.exe". Register your .hlp files to winhlp32.

been there,
