So, this is really no big deal, but figured I'd at lest mention it. In Firefox on Linux (only place I've seen it so far), the header-bar and menu is messed up. Same version of Firefox on Windows displays fine, so....
The bug on affects the header-bar ID, and menutop class. For the menutop, the 'Profile' and 'Spark' links get carried down to the next line. I think the overall bug lies in the wrapper class. Disabling all the CSS for that class "sorta" fixes it.
A hack fix, is disabling the 'overflow: hidden;' entry in the file template_css.css for the #header-bar ID entry. That at least shoves the header back to the left, but doesn't fix the menu problem.
Image of Header - Top is normal CSS, bottom is with the overflow disabled.
Disabling the 'overflow: hidden;' on Chrome didn't affect the layout, so I would guess that other webkit based browsers (like Safari), would be fine, so I don't know if that's just an IE hack that got placed into the main CSS instead of in an IE only sheet. Don't have IE to test that theory. :/
