[Greasemonkey] Editing a script

[Steve Randles]

Hi all,

I have an installed script and according to what I just read online I should
be able to to click on tools/manage user scripts/  highlight the installed
script/click edit and be able to edit it and when I click save I should see
the changes immediately.

Thats said, when I click edit, nothing happens! What or where am I
doing/going wrong?

Thanks in advance for any help offered.
