IE8 – Sessions Overlapping

I recently ran into an issue with Internet Explorer 8 reusing sessions between new windows and tabs.  The behavior was somewhat different from previous version of IE, which followed this model:

  • Click IE shortcut from desktop, start->run -> New Session
  • Run iexplore.exe -> New Session
  • Click File->New Window -> Same session
  • Click “Open link in new tab” (IE7) -> Same session
  • Click “Open link in new window” ->  Same session
  • Window.open() ->  Same session

According to Microsoft the merging of sessions was designed to improve memory usage and reduce complexity.

So, if your application depended on this behavior,  how do you get it back?

There are a couple of ways.

First, and easiest, create a shortcut to the web application with “-noframemerging” as part of it.

Ex:  “C:\Program Files\Internet Explorer\iexplore.exe” -noframemerging

Or, you can edit the registry and make this the default setting.

(Note:  Editing the registry and break your windows install, make sure you back it up before you edit.  And of course, know what you are doing – I am not responsible for you or what you do.)

Open Regedit and navigate to:
HKCU\Software\Microsoft\Internet Explorer\Main\FrameMerging

Changing the value of this key will turn FrameMerging on and off.

0 = Off
1 = On

Exit Regedit and Reboot

From the Trenches – Clean Install Using Windows 7 Upgrade

My personal computer came with Windows Vista.  Most pre-installed computers also come with a ton of applications that nobody will ever use, mine is no exception.  Running a spyware detection on my computer, right after doing a system restore, warns of several applications that are “potential” spyware.  So, when I have the opportunity to re-install I prefer to use the latest upgrade I purchased, rather than doing a system restore and upgrading.  Doing a Windows 7 install from upgrade media has proven to be a little difficult.  Microsoft has changed the process such that an upgade cannot be used to do a clean install.  I understand the reasoning, everyone would purchase the lower cost upgrade – and do a clean install, thereby getting the full version for less.

The installer does not tell you this is a problem until you have formatted your drive, installed the new version and are trying to enter the product key.  Once you get to that point you’re, quite literally, stuck.  So what do you do?  You do have options, any of which are workable depending on your scenario.  These were my choices:

  1. Call Microsoft Tech Support
  2. Install Windows 7 upgrade, then upgrade the Windows 7 upgrade
  3. Install from the recovery CD or Original OS, and then do the upgrade
