Menu overlapping title div in chrome

It doesn't seem to happen on your demo site but in chrome my horizontal superfish menu appears over the top of the title bar.

I am using the orange theme and the only things I have done is to add the main menu superfish block to the menu region and replace the logo with a different one.

I found that removing line 54 from page.css fixed it (and didn't seem to break other sites).

#header {
  clear: both;
  /* height: 100px;  - This seems to break the header/menu/title area in chrome */
  padding: 60px 0 0;
}
