Well, guess they didn't port my changes to the MIX build branch in
time. I was working on it pretty close to that deadline.
setting was inetcpl->Advanced->Reuse windows for launching
shortcuts. The default was broken when I put my fix in, you may have to
check/uncheck the box once for it to register. I believe if you have that
checked it will open outside links in a new tab.
If my IE changes
are there, but just inetcpl didn't get updated. You can change
HKCU\Software\Microsoft\Internet Explorer\TabbedBrowsing ->
ShortcutBehavior to 0, 1, 2.
0 is new window
1 is new tab
It turns out depending on which version of IE 7 beta you are running one of
the two options above should setup Internet Explorer to open external links
(such as links in Outlook) to open in a new tab instead of opening a new window.
For me I was running an older version and thus need to set Internet
Options->Advanced->Reuse windows for launching shortcuts (Link to registry key if
anyone is interested) . When I first starting using IE 7, a few months ago,
I was trying to figure this out and I looked at this option but it was already
checked. To my surprise was PetKnep's little note that it was broke unless you
unchecked/checked that option. After doing that little step it started working
as I expected. This as been my biggest annoyance since I started using IE 7 and
I'm glad its now gone.
