This is again a matter of taste I'm afraid. I quite like it when outlook
opens attachments like jpgs for me etc. It basically opens files with the
associated program. The default action of a scriptfile is 'execute' not
view, users *can* rightclick and choose view however, so again it is the
luser that's the problem imho.
Since many people were complaining about this, they just didn't get it or
didn't want to educate the users they had to deal with, MS made a patch
for this years ago. The patch then causes the same behaviour as you
describe: you first have to save before you can do anything with the
attachment (though you will find most windows users saving and then
running anyway... )

I worked as an operator for a year, it seems almost *impossible* to
explain stuff like this too people. Ofcourse I was dealing with accouting
and marketing people... never had any trouble with the development
department ;)

As I said before: this is a matter of taste. I like the fact that, as soon
as I click on an attachment it is opened by Outlook. If I would need to
save every Word attachment, Excel sheet, JPG file etc I receive first it'd
drive me mad. (Ofcourse you get a lot less of these in Unix environments
;) The option can be turned of as I already mentioned....
People shouldn't 'expect' anything from a program, they should RTFM.
