It is possible to view topics both in the built-in browser and in an external browser. There are several advantages in using the built-in browser. For example, when you open a page with a changed forum topic, the built-in browser automatically scrolls the web page to the position where new posts were detected.

However, it may be useful to open a forum topic in an external browser in some cases. To do so:

1. Select the topic you want to open in an external browser and right-click it.
2. Select the Open the Selected Topic in the Browser item in the menu.

You can also open the topic in an external browser using the Open the Selected Topic in the Browser command from the Resource menu.

Note: The default browser installed on your system is used as the external browser. You can change this in the Windows settings.
