Could somebody please help me on this please. I have created a navigation bar http://cre8tivesource.co.uk/test/

I have tested this on Chrome, Firefox 15 and it looks good to me (WIndows 7)

My client is saying that the last navigation item (Sejours Linguistiques) is dropping onto a second line. She is viewing the site on a PC using Firefox 15 on XP.

Is anyone else seeing this problem, and could it be a problem regarding the fact that she is running XP?

If so is their some kind of fix I could use for this?

Hope someone can help me, much appreciated.

Many Thanks
