Textbox with a list

[Samuel]

There is a feature that works sometime in explorer (and other browsers) that
as you start typing you get a list options (Auto Complete)

I try to figure out why the same page will behave differently on 2 different
computers even if this page was filled in both computer, for some reason one
of the computer is not showing the list

What is the cause of it and how can it be changed?

Thank you,
Samuel
