I use Google Chrome and 1024 x 768 screen res and experience this issue in the site header.
It's been noticed before:http://www.sitepoint.com/forums/showthread.php?851594-Display-of-2nd-menu-and-breadcrumb-trailhttp://www.sitepoint.com/forums/showthread.php?846541-Some-More-Forum-Changes&p=5106423&viewfull=1#post5106423and is on the to-do list, I believe. @HAWK?
I thought that it was something that @TimIgoe; was looking at but it's possible that I am wrong. Tim, is this something that you're aware of and can do something about?
