I'd like to run a second instance of Opera as a different user because I didn't find any other way to have two instances running at the same time.

For this purpose I created a second user for Opera (with admin rights). Then I gave the main user full control over the Opera-User's folder (c:\Users\Opera2). Now the second instance of Opera starts when I run it as a different user but it hangs and nothing works. The window opens but the welcome tab is loading and loading and loading...

I guess my main account still does not have sufficient rights to run the other Opera. Do you know what else I have to set so that it works?
