Cross Browser Rendering Problems

Hi Guys,

Firstly, what a great theme, so easy to use and configure; great work! I am contemplating making a change to the theme on a full time basis, just now I'm at the testing and checking my plugins are compatible on the localhost dev environment here at home.

The only problem I have, is the cross browser rendering. Everything is great in Firefox, however Chrome, Safari and IE don't seem to be working out as well. Chrome and Safari to a lesser extent, and IE is the worst off.

See below screenshot. Any advice?
