Mail: inbox messages automatically being marked as read

I've been having trouble with Mail (6.6, Mountain Lion) for a couple of days. Emails land in my inbox and I get the 'ding' but I don't get the red counter on the dock and the message is automatically being marked as read. I've missed a couple of important emails because of this. Is there any way to fix it?



Thanks,



Rae
