I've got a problem with my gmail page on my Mac OS X. It's set to appear as soon as I turn on my computer, and just after I turned the computer on yesterday, I was going to click off an icon that popped up, but turned my head for a second while I clicked. I must have clicked the wrong thing, because when I turned back, my gmail page - which should be half incoming emails, and half a current email that I've clicked on, suddenly became an entire list of emails. Now, instead of being able to click on an email and have it open automatically, I have to open each one manually. What did I click and how to I reverse it?
