WP 3.2.1, ATA, 3.7.1
I am having the same problem that the ATA 3.6 people had with no spaces after punctuation. I have read on the forums about the bug fixes and that they were included w/ 3.7.
I have disabled all plug ins and tried switching to 2010 theme. The Problem does go away by switching themes.

what is the url?

How are you displaying that page? is it a template? Have you modified any code?
how did you install 3.7.1?

Fresh install of theme and wp.
I commented out a piece of code in default-widgets.php that auto-fills blank titles.
I don't understand the question "how are you displaying this page?"

I de- commented the code and replaced it still no help.
As for template, it is atalhualpa with most of the style turned off from the dashboard.

I can tell that that page is a 'page' page, and I see the issue with the missing spaces, yet when I click on the 'home' link, I'm taken to teh home page with the same info AND it has the spaces. The only difference is the sidebar is missing.

So what is the difference between the two?

also you have something (a plugin?) that is compressing the source. Try removing it
