I didn't say "Unix Kernel." I said "Unix." By that I meant the entire
system - including the GUI - whqatever it happens to be. I was
pointing out that the problem seems to be associating executables with
the matching data file. That is a problem *all* OS's have. The Mac
seems to do a better job than most. MacOS seems to have a clear
separation of creators and documents, but I'm not an expert.

That's why I *said* the word 'had.'

I pointed out that the problem was in the individual data viewer
program, and not in the kernel. If we are going to be talking about
problems, we have to distinquish between the kernel, GUI's, and
applications. Alun already made this point and I was expanding on it.
