Thanks for replying. I am aware of holding Ctrl and left clicking. But it's not an acceptable solution for me if there is a tweak or extension that can enable single left clicking on the link.

I have an ancient program that adds links to IE's Command Bar that, in appearance, look similar to Chrome's bookmarks bar's links but which, by default open the links in a new window with a single left click. If it's possible, this, or in a new tab, would be what I am looking for.

Jim.
