Lost HTML Capabilities when upgrading from 4.6.1 to 4.6.2

Administration Reference area - administer >> forums
I am using HTML tags formatting such as bold fonts and hyperlinks in both the forum containers (“add containers”) and in the forums (“add forum”). After upgrading from Drupal 4.6.1 to 4.6.2, I lost HTML formatting capabilities in these areas. Now these areas show the HTML tags and not the intended HTML formatting.

The following is an example forum container:

In Version 4.6.1, the html tags worked and appeared as follows:

If you want to or have developed Add-ons or Plug-ins, post the information in this section. More information can be found here: Add-ons and Plug-ins

After 4.6.2 upgrade. The HTML tags no longer work and now appears as follows:

If you <b>want to</b> or <b>have</b> developed Add-ons or Plug-ins, post the information in this section. More information can be found here: <a href="?q=node/13"> Add-ons and Plug-ins</a>

Does anybody know how to restore the HTML capabilities in these areas?
