Problem with Form layout in Google Chrome

[starryUK]

Hi

I'm hoping someone will be able to help me with this CSS Problem.

Here is the page:

(The problem appears on all the pages on which I have the search box.)

The problem is with the search box in the header on the right hand side. In Firefox/Safari/Opera/IE the Go sits beside the text field without any problems, in Google Chrome it drops down to the line below which pushes the telephone number out of line. If I eliminate all spaces between the form fields then the problem goes away, but obviously it looks awful.

Anyone have any idea what might be causing the problem?

Thanks very much,
Jennie
