Opening Opera as user

[Rem P Roberti]

I installed linux-opera, and I guess I made a mistake by opening it the 
first time as root, when I should have opened as user.  At any rate, I 
can now only open the browser as root, and when I do I get this message:

opera: $HOME set to /root. Use -personaldir if you do not want to use 
/root/.opera/

Can someone give me a heads up on how to fix this, as the above message 
is a mystery to me.

Thank you!
