I'm sorry for this - it's very strange. I can't replicate the problem on my machine, so I'm guessing it must be caused by a particular combination of browser and operating system. In order that the techies can help, we'll need to gather a few details about your system, so they can attempt to replicate the issue before finding a solution.
It would be very helpful if you could visit the following site, and just input your name and email address where prompted and also our email address (firstname.lastname@example.org) in the ‘Recipient’s email’ in the fields at the top of the page:
The site automatically detects your browser and operating system – you don’t need to add any technical details yourself. All very quick and easy.
If you can send us that then we’ll do our best to resolve the problem for you.
