I am trying to do something that can be simple but have not been able to find it out on any manual.
I want a button to open a new window on the browser on a pop up style. The button should link to a smaller window emerging and leaving the original page on the background. It would be a window containng some information and once you see it, you just close the window and stay back to the original page.

How can I do that please?

Thanks in advance to anyone.

You can do that using Dreamweaver's "Open Browser Window" behaviour. Go to Window>Behaviours - click on the + and from the dropdown select Open Browser Window. If it is greyed out go to Show Events For and select IE5 or later.

You can also set the target state on the link/button to blank, like this:

<a href="#" target="_blank">Your Link/Image</a>

When clicked on, this will open the link in a new window.
