Tabs are one of the best new features in Internet Explorer 7.  I like them because they keep my task bar clean of extra Internet Explorer instances. The only problem I have is with pop-ups that are on my allow list such as when I write a new message in Outlook Web Access.

Follow these steps to configure Internet Explorer 7 to always open up pop-ups in a new tab instead of a new browser window:

1. While IE7 is running, click on Tools and select Internet Options.
2. On the General tab under the Tabs section hit Settings.
3. Under the When a pop-up is encountered section, select Always open pop-ups in a new tab. I also like using the Let Internet Explorer decide how pop-ups should open option because of some web sites I visit.
4. Hit OK and you are finished.
