No cap after a period in Dragon Dictate 4

In Dragon Dictate 4, when I say "Hello world period this is a test period", it outputs:

Hello world. this is a test."

There is no cap after the first period. Is there any way to fix it?

This issue affects most programs: Evernote, the default Mac OS X mail application, Safari, Latexian, etc. There is no such issue using Dragon's notepad or Google Chrome.

Obviously I don't want to have to say "Cap" after each period.
