E-mail/SMS/MMS inbox doesn't start from the top

I have all my email/sms/mms messages going into one folder. Well when I go into that folder for some reason it doesn't go to the top of the folder. This is kind of annoying when I don't check my emails everytime I get one. I will wait for a few when I'm at work. Is there any way to set it so it goes to the top of the inbox when I open the folder?

Thanks in advance

the bottom tool bar has "arrow up" and "arrow down" for that purpose. mine usually starts back at what ever was the last message i read unless i go "menu>close"
