After opening Mail I start to receive emails that I opened earlier.
I recently moved from the PC to the Mac and so far I'm loving it but I'm having trouble with Mail. I configured Mail with my Gmail account. Mail synchronized all my emails but now when I open Mail it starts sending emails that I've already received and opened in Gmail, one after the other, continuously. Last time I received more than 20 emails in my BlackBerry that I've already had received. Why is this happening and how can I solved it? Any help will be welcome.
MacBook Pro, Mac OS X (10.6.1)
