Open a new explorer window using its own session cookie by selecting File -> New Session from the Menu Bar in an existing browser window. (IE9 Users may have to enable the Menu Bar first by right clicking the browser header frame and selecting Menu Bar.)
Run from the command line adding the -noframemerging parameter e.g. Start -> Run -> iexplore -noframemerging
Create a new IE8 icon adding the -noframemerging parameter e.g.
Start -> Program Files
Right click on the Internet Explorer icon and select Properties
Add -noframemerging to the end of the link in the Target field e.g."C:\Program Files\Internet Explorer\iexplore.exe" -noframemerging
