Tabs vs. Spaces problems in comments

Working with Javascript, I have two problems:

1. When I've used tabs to indent some text in a comment and I hit return to recreate a new line, it de-indents it one tab and then adds a trailing tab character after my cursor. How can I turn this off?

2. On the Tabs and Indents tab of the Code Style preferences window, I've chosen to use Tabs. However, when I format my code, it still replaces my tabs with spaces in all of my comments. How can I setup code formatting to use tabs everywhere?

Can't seem to find the setting to change these things. 

Thanks!
