Is there a way to check who messages are from on Facebook without losing red notification?

[yeah]

I know that when a Facebook user sends you a message, a red notification will pop up in the upper left hand corner the next time you log in. I want to be able to click on the red notification and see who the message is from, for example while I'm on my work computer at lunch, but I don't want the notification to go away until I actually go into my actual inbox on my home computer. When I click on the notification, it shows a preview of the message and then I no longer see the notification the next time I log in (even though I only read the preview).

Is there any way to see who a message is from without losing the red notification? Thanks and sorry if this was confusing.
I don't receive emails that notify me when I receive a comment/message/friend request. I know you can opt to, but that is just one more email I would have to delete. I might have to do this though.

And I'm specifically referring to messages, not comments. Thanks!
