Centered Popup Window Extension

For years I used this extension for GoLive to simply launch a window, sized accordingly, no toolbars, address bar, etc, and CENTERED precisely in the middle of the screen. It worked perfectly. It was written by Rasmussens Design Actions.

The only extension I can find so far for Dreamweaver re-locates a popup window after it's launched, so the window scoots into place - pretty annoying.

And, this is a two-step process - I have to add two scripts. One to launch the window from the main page, and another script in the actual popup window page to center it. Kind of a pain.

Can anyone point me to a good, all-in-one extension for Dreamweaver that can do this?

Thanks!
