Multi Google Talk

Just follow the simple steps Below:

1.Right click on google talk shortcut,
2.click on properties
3.Go to shortcut tab on google talk properties window
4.on the target textbox,add in the /nomutex to the end of the line so that it looks like below(or you can simply copy and paste the below syntex and replace the original)
"c:\program files\google\google talk\googletalk.exe" /nomutex
5.click on ok

I didnt have to do anything after this and clicking on the shortcut multiple times just gave me different google talk window.
