You can change the default page that opens for new tabs by going Tools->Internet Options, selecting the General tab, and clicking Settings in the Tabs section. The last option in the first section can be checked so that your homepage is opened instead of a blank page. If you have multiple homepages set up it will only open the first one.
Hope this helps,
I just upgraded to IE7 from IE6. Just a quick question, I like the TABS in IE7, is there a way when I click on a "NEW TAB" that it opens something other than ABOUT:BLANK? My homepage or is there a way to set another page I often use when I click on new tab when I have other pages open?
Thanks for any help,
