Powershell host.ui.prompt doesn't pop up a dialog box when run from the command line

Question

This is a follow-up to my earlier question

I have written a script which uses $host.ui.prompt.
The script runs fine when I run it from my editor (PowerGUI), and the dialog box pops up nicely to prompt the user for input, like this:

.

However, when I run it from a command line (powershell .\script.ps1), no dialog box pops up: instead, command line prompts appear, like this:

I expected that the script would pop up the nice dialog box for me as before.

What am I missing?

The $host.ui.prompt like the name says, is specific to the host implementation. PowerGui have impemented a custom host / prompt which is GUI based. The default prompt on the console is the text one that you see.
