gmail page set up

[Stareader]

I have a Mac OS X with the gmail page coming on automatically when I turn on the computer. I had just turned the computer on yesterday, and was clicking off an icon, but as I did, I turned my head away from the computer, and when I turned back, I suddenly had a gmail page that showed my entire list of gmails, instead of leaving the half page blank so I could read the emails I click on. Now, I have to click on to the email and manually open it instead of being able to have it show up the second I click on it, and I can't get this entire list of gmails to recede back to being the half page it's supposed to be. I obviously clicked on something I shouldn't have, does anyone know how to reverse this?

I presume you're talking about Mail.app?
