If you view the new blog i am setting up http://ryanjz.wordpress.com in Chrome the header image is perfect. If you open the blog in IE8 or Firefox 3 and 4 beta the header image is 2px taller and obscures the dotted line.
Any tips on correcting this? I have already triend several images including pre-cropped 712x80 originals. If i submit a 78px height it stretches the image and the result is the same.
The blog I need help with is ryanjz.wordpress.com.
