Start

Every time you start Opera, the start-up dialog lets you choose which windows to start with.

If you want to start the same way every time, disable the start-up dialog and select how to start up here.

When you exit Opera, you can:

Have Opera ask you if you really want to exit
Automatically close your dial-up connections if you have a non-permanent Internet connection
