I am hoping someone can tell me how you navigate email in Sparrow? I'm a huge proponent of keyboard navigation. In every other mail app I have ever used you can simply hit the Space bar to scroll the current email message until you hit the end, then it selects the next message for reading. With Sparrow, it opens the selected email in a new window. And that's fine. But when you press Space bar instead of scrolling it so you can read it, it closes the window. The only way I can scroll the message is to use my mouse/trackpad/down arrow. It's frustrating.

I assume they are using the space bar to quick look like in the finder.
I would find an another Mail client or another key to press.
