Location 'bubble' info box bug

Hi,

I’m having a problem with the info ‘bubble’ overlay – ie the info box that displays when you click on a location pin on the map.

The text isn’t wrapping inside the div when it’s uploaded to the server – it’s displaying fine in my local version and all the files are exactly the same. Note I’m using custom CSS, but it has the same problem with the default settings.
Has anyone else had problems with this, or come across a similar behaviour when moving things from local to hosted?

Thanks,
Dave
