I think I might be losing my mind. The site I just finished http://jefferson-center.org seems to be having some select nav bar issues. The issue seemed to come up this week. I haven't made any style changes, only the normal updating of plugins.
Chrome for mac (my default browser) seems to put a 1 or 2 pixel space between the hover state on the top menu and the red bar. I can't seem to duplicate the issue on any other mac browser (safari and firefox), nor does it show up on any windows browsers (firefox, chrome, IE). It's also very weird that my local development (through MAMP) doesn't have this problem.
Obviously my next step is to disable all plugins and figure out which one updated and caused the issue. Can anyone else confirm this is a problem?
