Hi all,
I've just had a quick look with Google Chrome browser, and all still seems OK.
So the problem could be an upgrade on a different browser (Internet Explorer maybe?). So I will investigate further.
The code at this site has remained unchanged.
If people could report what browser they are using when things don't seem right - that may help speed up my diagnosis.
