I have seen questions coming out of this forum for handling Browser's having same name.

I have noticed that if I have a browser for eg. QA Forums, and on clicking on any link a popup browser with the same title popups up, QTP identifies it as a duplicate and adds creation time as its unique property.

I found another workaround to this assuming the fact that the popup window is a different url. Using the browser with just the openurl also works. So its like Browser("openurl:=http://www.google.com/something").

This is espcially useful when you are using Keyword driven or object driven approaches.

Hope this helps.
