IE 8 Separate Instaces/Windows?

When I was using IE7 I could log into my personal MySpace account, click on the IE icon to open another window and I could now log into my music MySpace account. It would keep things separate for each window, while maintaining the same instance in tabs in the window..i.e. I could open separate tabs for say my friends lists and they would stay relevant to the window it was in. Now when I try this, I just get the standard already logged in page.

How do I do it again so its like a diffent instance or connection for each window..or do I need to go back to IE7?

Anyone...?

Use the -nomerge option in the command line for IE. IOW....right click on ur shortcut icon and go to properties. Where is says target...add -nomerge at the end, after the quotes.....example:

"C:\Program Files\Internet Explorer\iexplore.exe" -nomerge

This worked for me...
