Subject: Edit File Type dialog box question 11/13/2005 6:15 PM PST

Following instructions on the Windows site, Article ID : 321379, to "print
a directory listing", I added the command to the file type dialog by clicking
"New". After clicking OK, I tried out the command but then wished to alter
it to save the listing as well. However, it was then impossible either to
edit the command or delete it- both options were greyed out. Clicking on
"Default" made it much worse.

How do I edit or delete a command in this dialog box?

I have the appropriate administrative powers but Windows seems to restrict
my access to further modification of this box.

The computer runs XP professional SP2

Thank you for your help.
