Homepage different from Chrome to IE/Firefox

Hi to all, I use the hottennis template..
I don't know because I see two different situation in the homepage of this site www.aceopentennis.it/

With IE or Firefox I see correct, with Google Chrome no... Look the "Big Header (Home)" in top1. The words "ace open tennis" are in different position.

Why?

Thank you

Google chrome , IE 10 and latest FF display it correctly

Sure..
look the attach..

In my pc and in others it's different.. look the attach.. the words "ACE OPEN TENNIS" in chrome are higher.

thank you

Not sure on our demo text is on same position, you can send us link so we could check

The site is www.aceopentennis.it

In layout.css

.mp_top1 {
padding-top: 140px;
}

add position: absolute;

that could create problems for other things so think is that is nessesry
