Adding calculators to my own web pages

Hi Will,

I would have thought that the disclaimer could be shown once a day, I'd certainly be happy with that.

I've carried out a quick survey of the browsers I have to hand; Firefox and Chrome appear to be fine, but both IE6 and IE8 show the disclaimer every time. The URL I'm testing is http://dl.dropbox.com/u/1919767/CryoWiki/CryoWiki.html#Radiation

Regards
