Opera

Clicking on "mailto" or "news" links causes Opera to launch Microsoft Outlook Express. Some users report that they would prefer either to have an integrated e-mail or news client such as Netscape or the ability to select an e-mail and news application. If you wish to do this, you can follow the instructions below:

Choose your e-mail and news client in the Internet Control Panel. In Eudora, you choose your browser by holding down option while clicking on link in an e-mail. Opera 7 includes integrated news and mail.
